Benefits Of Dual Plate Check Valves

Product Characteristics Water Hammer PreventionWater hammer commonly occurs when

a valve is closed suddenly at an end of

a pipeline system, and a pressure wave

propagates in the pipe. Terofox Check Valves

have quick response by closing discs. It

decreases the frequency of water hammer

condition.

Non SlammingWhen swing check valve is closed, the reversal

of fluids in the pipeline will slam the plates

(discs) against its seal, and would cause the

noise, shortening the valve service life in many

cases. Terofox Dual Plate Check Valves have

outstanding springs against the plates (discs)

to resist the reversal of fluids, causing the

plates(discs) to close slightly.

Simplicity InstallationMost of traditional swing check valves are

heavy and closed improperly. Also they take

more space than dual plate check valves.

Dual plate check valves are able to be

installed in any position, horizontal or vertical.

Why Choose Our Dual Plate Check Valves ? Small space available, easy installation, quick closing to reduce

water hammer

Cost-efficient

Diversity of connections ( Wafer, Lug, Flange )

Wall thickness is according to B16.34 / API594

Quality assurance

High CV & Low Pressure DropTerofox Dual P late Check Valves take

advantage of lower pressure drop with

functional operations.

Seat LeakageTerofox Valves are genera l ly tes ted in

compliance with international standard such

as API598 which has specified the permission

of leakage rate in 3 c.c./inch of bore /mm

( in hydraulic test ) by metal to metal check

valves. 700 c.c. leakage rate of permission by

air test.

Sour Gas ServiceTerofox Dual Plate Check Valves are able

to meet the requirement of NACE MR0175

treatment.

1.The rate or rates of seat test leakage for each valve type shall be as specified in the valve product standard.2.These leakage rates only apply when discharging to atmosphere.3.Leakage rate1 is intended to apply to metal seated valves producted for internal stock,sale via a stockist,or

a warehousing opration. 4.Leakage rate2 is intended to apply to metal seated valves on more critical services. 5.Leakage rate3 is intended to apply,for example,to"elastomeric or polymeric"(soft seat) seated valves.

FLOW

The valve must be installed as following to work properly in a vertical pipe line. It has to set the rib of wafer check valves vertically.B

The pipes connect the dual wafer check valves have to be in compliance with flow direction as indicated on body valve.A

As long aspossible

PLATE

It's not allowed to install a reducer in front of or behind the wafer check valves, needing a space of 6~8 times at least the valve diameter (6~8D) or more.C

Leaving a space as long as possible between elbow and wafer check valve if the wafer check valves installed nearby the elbow ( no recommended ); otherwise the plate will be opened incorrectly in the downstream of pipeline.

Inspection and Test

Concentric Butterfly Valves, Rubber

1. Butterfly Valves shall be tested as per ANSI B16.34, MSS SP-61, API598, ISO 5208 Terofox would organize the inspection according to API 598 if customers didn t require prior to order.

2. Butterfly Valves should be seated test as per MSS SP-61 or ISO 5208 with no leakage occurrence for resilient seated.

3. If butterfly Valves are required by stem 17-4PH material, Terofox will test in compliance with MSS SP-61 or ISO 5208 only

A butterfly valve is a valve which can be used for isolating or regulating flow, Operation is similar to that of a ball valve, which allows for quick shut off. Butterlfy valves are currently favoured by customers due to lower cost compared to other type of valves as well as bring lighter in weight. It means easy installation with simple operation. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. Terofox has several kinds of butterfly valves, each adapted for different pressure, application and different usage.

Why Choose Our Butterfly Valves ?

Technical Data

Simple and compact contrcution, quick 90 degree on-off operation. Minimized

operating torque value, with energy saving.

Bubble-tight sealing with no leakage for soft seat butterfly valve.

The connection of driven part conforms to ISO 5211.

Wide selection of materials, applicable for various medium.

The valve body and disc are precisely machined which results in low operating torque

and long service life and reliability.

Could be disassembled, material-specific recycling possible.

Could be installed at the end of pipe for lugged type butterfly valve.

Terofox Butterfly Valve is made with a "Phenolic Backed" not "Soft Backed Seat".

The phenolic backed seat is non-collapsible, streth resistant, blowout-prood and easily replaceble.

The soft backed valve has a wider seal section between seat and flange while mounted, but soft backed seat is subjet to distortion during installtion and closing and is contributed to shaft leakage and high torque.
