This test is a snapshot of system performance. Flow and pressure are affected by a variety of factors including: tank and reservoir levels, pump and valve settings, demand variations, and future changes to operational settings. The static pressure at this location may be as low as 80% of the maximum static pressure as calculated using the Max Static HGL.

1. DESCRIPTIONThe Viking Model F-2 Dry Pipe Valve is a latching differential valve used to separate the water supply

from the dry pipe sprinkler system. The valve combines a positive latching clapper and air plate assem-

bly, with a differential air to water seat design. The latching clapper and air plate assembly provides a

positive mechanical seal for the air pressure in the dry pipe system. The differential design allows an air

supply of moderate pressure to control a higher water supply pressure. When the air pressure in the dry

pipe system is lowered suffi ciently to destroy the pressure differential, the valve opens allowing water

to enter the dry pipe system.

The valve is also designed to operate a water motor alarm and/or an electric pressure alarm switch.

The Viking accelerator with external Anti-fl ood Device can be used to speed the operation of the valve

on large capacity systems or where faster action is required.

4. INSTALLATION For proper operation and approval, the valve must be trimmed in accordance with Viking Model F Dry Valve Trim Charts.

The Model F-2 Dry Valve must be installed in the vertical position as shown in Figure 2.

Air or nitrogen supply to the dry pipe system must be clean, dry, and oil free.

Automatic air supplies must be regulated, restricted, and from a continuous source. (Refer to Table 2) A Viking Air Maintenance Device

should be installed on each system equipped with an automatic air supply. Never exceed 60 PSI (4.1 bar) pressure in the system pip-

ing with the dry valve clapper closed.

The dry valve must be installed in an area not subject to freezing temperatures or physical damage. If required, provide a valve house

(enclosure) with adequate heat around the dry valve and trim. Freezing temperatures and/or excessive pressure will damage the dry

valve member assembly.

When corrosive atmospheres and/or contaminated water supplies are present, it is the owner’s responsibility to verify compatibility

with the Model F-2 Dry Valve and associated equipment.

Consider installation of the Viking Accelerator and Anti-fl ood Device. An accelerator (quick opening device) is recommended on all

differential dry pipe valves and is required on dry pipe systems of certain capacities. Refer to Installation Standards and Authorities

Having Jurisdiction. If an accelerator is to be installed, verify that the appropriate Trim Chart is used. Prior to installing the valve, thor-

oughly fl ush the water supply piping to verify that no foreign matter is present.

A. General Installation InstructionsVerify that necessary Trim Charts and Technical Data for the dry valve and associated equipment are available.

Remove all plastic thread protectors from the openings of the dry valve.

Apply a small amount of pipe-joint compound or tape to the external threads of all pipe connections required. Take care not

to allow any compound, tape, or other foreign matter inside any of the nipples or openings of the dry valve or trim compo-

nents.

Install the Model F-2 Dry Valve and trim piping according to the current Model F-2 Dry Valve Trim Chart provided with the

Trim Package and the Viking Engineering and Design Data book. The Model F-2 Dry Valve must be installed in the vertical

position.

When installing a Viking Accelerator and Anti-flood Device in conjunction with the Model F-2 Dry Valve, refer to the appropri-

ate Viking E-1 Accelerator Trim Chart provided with the Accelerator Trim Package and the Viking Engineering and Design

Data book.

When a Viking Accelerator is installed on the Model F-2 Dry Valve, the dry system air supply must be connected as shown

on the Model E-1 Accelerator Trim Chart.

The Viking external Anti-flood Device is required when a Viking Accelerator is installed on a Dry Valve according to the

Model E-1 Accelerator Trim Chart.

Hydrostatic Test:CAUTION: THE DRY VALVE CLAPPER MUST BE LATCHED OPEN DURING PERFORMANCE OF THE HYDROSTATIC TEST.

Do not perform a 200 PSI (13.8 bar) hydrostatic system test with the dry valve clapper in the closed (set) position.

Never exceed 60 PSI (4.1 bar) air pressure in the system piping with the dry valve clapper closed.

DO NOT expose the Viking Accelerator to the hydrostatic test. For warnings and considerations regarding hydrostatic testing of the

Viking Accelerator and other system components, refer to Technical Data for the equipment used.

GROOVE/GROOVE


When the dry pipe system is ready to be placed in service, verify that all equipment is adequately heated and protected to prevent

freezing and physical damage.

Verify that the water supply main control valve supplying the dry valve is closed.

Open the main drain valve (located on the inlet of the dry valve).

Drain all water from the dry pipe system. If the system has operated, or if water has entered the system, open all auxiliary

drains and the system test valve. Allow enough time to completely drain the system. Perform steps 4 through 10 to set the

dry valve and/or inspect the internal operating parts of the dry valve.

Verify that the dry pipe system is not pressurized.

Use the Dry Valve Reset Bar/Wrench, part number 02977BM, to loosen and remove hand-hole cover bolts (21). Remove

hand-hole cover (24).

CAUTION: CLAPPER ARM ASSEMBLY (8) AND CLAPPER ASSEMBLY (5) ARE SPRING LOADED TO OPEN. NEVER PLACE HANDS INSIDE THE DRY VALVE IF THE CLAPPER ASSEMBLY IS LATCHED CLOSED.

To release a latched clapper assembly for service:

Insert the re-setting tool through the hole in hook assembly (15), across the fulcrum cast on top of clapper arm assembly

(8) until the re-setting tool contacts the stopping boss on top of clapper arm assembly (8) (see Figure 2C).

Apply a downward force on the end (outside the valve) of the re-setting tool. Hook assembly (15) will slide toward the hand-

hole and off clapper arm assembly (8). Clapper arm assembly (8) and clapper assembly (5) will forcefully open, impact

against latch (2), and latch in the open position.

NOTE: INSPECTION AND CLEANING PROCEDURE STEP 7 BELOW IS CONSIDERED PART OF THE ANNUAL TRIP TEST.

Inspect and clean the internal parts of the valve. Give special consideration to the water seat (16), air seat (20) and clapper

rubber (19). Wipe away all contaminants, dirt, and mineral deposits. Do not use solvents or abrasives. Operate all parts to

test freedom of movement. Renew or replace damaged or worn parts as required.

CAUTION: NEVER APPLY ANY LUBRICANT TO SEATS, GASKETS, OR ANY INTERNAL OPERATING PARTS OF THE DRY VALVE. PETROLEUM BASED GREASE OR OIL WILL DAMAGE RUBBER COMPONENTS AND MAY PREVENT PROPER OPERATION OF THE DRY VALVE.

To set the dry valve clapper. (Refer to figures 2 & 3)

Raise the latch (2) to release spring loaded clapper arm assembly (8) from the latched open position.

Move the clapper arm assembly (8) down toward the horizontal position (see Figure

2-B).

While holding spring loaded clapper arm assembly (8) down, insert the re-setting

tool through the hole in hook assembly (15), across the fulcrum cast on top of clap-

per arm assembly (8) until the re-setting tool contacts the stopping boss as shown

in Figure 2-C.

Apply a sharp upward force at the end of the re-setting tool. Hook (15) will slide

forward on the re-setting bar and latch the clapper closed with a positive setting

action (see Figure 2-C).

Priming water is not required and may not be desirable where clean, good quality fresh

water is not available. If priming water is desired, fill the dry valve with water to the bot-

tom of the hand-hole. Verify that the intermediate chamber of the dry valve is free of

water. No water should fl ow from the drip check when the plunger is pushed.

Visually inspect hand-hole cover gasket (25). Verify that it is in good condition.

Re-install hand-hole cover (24), gasket (25), and hand-hole cover bolts (21). Tighten the bolts using the Dry Valve Reset

Bar/Wrench, part number 02977BM.

Close all auxiliary drains, the system test valve, and the priming water level test valve on the dry valve trim. The main drain

(located on the inlet of the dry valve) should remain open.

If equipped with a Viking Accelerator and external Anti-flood Device:

Close the ½” (15 mm) anti-flood isolation valve.

Observe the air pressure gauge on top of the accelerator. The gauge must read zero before the accelerator will auto-

matically reset. It may be necessary to loosen, remove, and re-install (use the appropriate wrench) the air gauge to vent

trapped air pressure from the upper chamber.

Open the dry system air supply and establish desired system pressure. See Table 2 for suggested air pressure to water pres-

sure settings. NEVER EXCEED 60 PSI (4.1 bar) AIR PRESSURE.

Verify that the intermediate chamber of the dry valve is free of water. No water should flow from the drip check when the

plunger is pushed.

If equipped with a Viking Accelerator and external Anti-flood Device: When pressure on the accelerator air pressure gauge

equals the system set pressure, OPEN and secure the ½” (15 mm) anti-flood isolation valve.

Slowly open the water supply main control valve.

When flow is developed from the main drain, CLOSE the main drain valve.

Fully open the water supply main control valve.

Secure all valves in their normal operating position.

Notify Authorities Having Jurisdiction and those in the affected area that the system is in service.

5. OPERATION (Refer to Figure 2)

The clapper (5) and air plate (11) assemblies combine to form a fl oating member assembly. With the clapper assembly (5) latched

closed, system air pressure forces the member assembly down, sealing the water seat (16) from the intermediate chamber. When

a sprinkler operates, the system air pressure is reduced. When system air pressure is reduced to the differential tripping point of the

valve, water supply pressure in the inlet chamber lifts the member assembly off the water seat (16) and fl ows into the intermediate

chamber. As the member assembly continues to rise, the latching hook (15) is forced against operating pin (23), which causes the

hook (15) to pivot on hook rod (6b) and unlatch the clapper. The clapper is spring loaded and swings to a full-open locked position

(See Figure 2-A).

When equipped with the optional Accelerator and external Anti-fl ood Device, a drop in system air pressure causes the Accelerator to

operate. Operation of the Accelerator causes the Anti-fl ood Device to open allowing system air pressure to enter the dry valve interme-

diate chamber. This immediately destroys the pressure differential, causing the member assembly to rise faster.

The intermediate chamber is normally at atmospheric pressure and is connected to the alarm line. When the valve trips, the intermedi-

ate chamber and alarm line are pressurized with system water pressure, activating alarms connected to the dry valve trim.

ABNORMAL CONDITIONSSee Table 3

6. INSPECTIONS, TESTS AND MAINTENANCENOTICE: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE PROTECTION SYSTEM AND DEVICES IN PROPER OPERAT-ING CONDITION.

The Viking Model F-2 Dry Valve and trim must be kept free of foreign matter, freezing conditions, corrosive atmospheres, contaminated

water supplies, and any condition that could impair its operation or damage the device.

It is imperative that the system be inspected and tested on a regular basis. The frequency of the inspections may vary due to con-

taminated water supplies, corrosive water supplies, corrosive atmospheres, as well as the condition of the air supply to the system.

For minimum maintenance and inspection requirements, refer to NFPA 25. In addition, the Authority Having Jurisdiction may have

additional maintenance, testing, and inspection requirements that must be followed.

WARNING: ANY SYSTEM MAINTENANCE WHICH INVOLVES PLACING A CONTROL VALVE OR DETECTION SYSTEM OUT OF SER-VICE MAY ELIMINATE THE FIRE PROTECTION CAPABILITIES OF THAT SYSTEM. PRIOR TO PROCEEDING, NOTIFY ALL AUTHORI-TIES HAVING JURISDICTION. CONSIDERATION SHOULD BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AR-EAS.

I. INSPECTIONWeekly inspection is recommended. If the system is equipped with a low air (or nitrogen) alarm, monthly inspections may be ad-

equate.

Compare test results with previous flow information. If deterioration of the water supply is detected, take appropriate steps to

restore adequate water supply.

Verify that normal water supply pressure and system pneumatic pressure have been restored, and that all alarm devices and

valves are secured in normal operating position.

Notify the Authority Having Jurisdiction that the test is complete. Record and/or provide notification of test results as required

by the Authority Having Jurisdiction.

C: Priming Water Level, and Low Air Alarm TestQuarterly testing is recommended to verify that water is not present above the Priming Level Test Valve in the dry valve trim.

Quarterly testing of low air alarms is recommended.




Close the water supply Main Control Valve supplying the dry valve.

Open the Main Drain Valve (located on the inlet of the dry valve).

If the dry valve being tested is equipped with a Viking Accelerator and external Anti-fl ood Device installed according to Viking Model

E-1 Accelerator Trim Charts, performing steps 6 or 7 of this test will cause the accelerator to operate. A burst of air from the vent in the

bottom of the accelerator will indicate operation of the accelerator. However, with the water supply Main Control Valve CLOSED and

the Main Drain Valve OPEN, operation of the accelerator should not trip the dry valve.

Dry Valve Priming Water Level Test:

Verify that the water supply main control valve is closed and the main drain valve is open.

Fully open the Priming Level Test Valve in the dry valve trim to check for the presence of water. If the presence of water

is detected, the system may not have been properly drained. Perform steps 1 through 3, and 11 through 15 of paragraph

10, PLACING DRY VALVE IN SERVICE, and repeat this Dry Valve Priming Water Level Test.

If/when no water is detected and the test is complete, continue to step 8.

Low Air Alarm Test:

Verify that the water supply main control valve is closed and the main drain valve is open.

Gradually open the Priming Level Test Valve in the trim of the dry valve to simulate operation of the Dry System. Observe

and record the pressure at which the low air alarm operates.

Close the Priming Level Test Valve.

If the dry valve being tested is equipped with a Viking Accelerator and external Anti-flood Device:

Close the ½” (15 mm) NPT Anti-flood Isolation Valve. Air will continue to flow from the accelerator after it has operated

until step “b” below is performed.

Loosen (use the appropriate wrench), and remove the Accelerator Air Gauge to release pressure from the upper chamber

of the accelerator. When the accelerator re-sets, re-install the accelerator air gauge.

Perform steps 13 through 20 of paragraph 4-B INSTALLATION, Placing the Valve in Service.

TRIP TESTSPartial Flow Trip Tests are conducted with the water supply main control valve partially closed to minimize the amount of water enter-

ing the system during the test. Performance of a Partial Flow Trip Test is recommended during warm weather at least annually except

when a Full Flow Trip Test is conducted. Partial Flow Trip Tests may verify operation of equipment and devices but do not simulate

operation of the system in fi re conditions.

Full Flow Trip Tests are conducted with the water supply main control valve fully open. The dry valve is operated by opening the system

test valve to simulate the opening of a sprinkler in fi re conditions. When the dry valve operates, the sprinkler piping will be fl ooded with

water.

Performance of a Full Flow Trip Test is recommended during warm weather at least once every three years. More frequent testing may

be required by the Authority Having Jurisdiction.

A. Full Flow Trip TestNotify the Authority Having Jurisdiction and those in the area affected by the test.

Inspect the rubber diaphragm for deterioration. If neces-

sary, replace the diaphragm.

Clapper will not latch

Incorrect resetting tool

Verify that the re-setting tool used is smooth and of the

proper strength and diameter* to provide the required

force at the appropriate angle to cause the latching hook

to slide over the clapper arm when setting the dry valve.*The Viking Re-setting tool is a 3/4” (19 mm) diameter cold rolled steel bar, chamfered at one end and a standard 15/16” hex-socket on other end. (PN 02977BM)

The hook not sliding on the

re-setting tool

File or grind the re-setting tool. Remove any rough spots

to provide a smooth sliding surface and proper clear-

ance.
