627 Series Self-Operated Pressure Reducing Regulators

Fisher Controls

Bulletin 71.1:627

The 627 Series self-operated pressure reducing regulators (figure 1) are for low and high pressure systems. These regulators can be used with natural gas, air, or a variety of other gases. Performance characteristics vary according to construction (see the Specifications table).

FeaturesD Internal Relief ValveType 627R and 627MR regulators have an internal relief valve, which in many cases eliminates the usual requirement for an external relief valve, thereby reducing equipment and maintenance costs. Refer to the Specifications table for capacity data.

D Type 627R and 627MR Travel StopThe internal relief valve still works if the disk or linkage fails. The pusher post (figure 2) contacts the travel stop of the lever retainer and, as the diaphragm continues to rise, it opens the relief valve. D Relief Operation IndicatorA rubber cap (figure 3) slipped on the vent assembly pops off when the relief valve opens, indicating the relief valve has opened since the last inspection. D Easy to MaintainTrim parts can be replaced without removing the regulator body from the pipeline. A twobolt connection between the body and diaphragm casing simplifies disassembly for maintenance. D Installation AdaptabilityThe diaphragm case and/or regulator body can be rotated in any of four positions to allow regulator installation in locations with limited space (figure 10). The regulator may be installed in any position without affecting operation as long as the spring case vent is protected from the elements. D Application VersatilityThe different 627 Series constructions can be used as farm tap regulators, regulator-relief valves, monitoring regulators, or high-pressure industrial regulators.

Product DescriptionTypes 627 and 627H Self-Operated Pressure Reducing Regulators The Types 627 and 627H regulators provide economical pressure reducing control for a variety of residential, commercial, and industrial applications. The regulator pitot tube located in a high velocity stream provides dynamic boost that compensates for outlet pressure drop (see table 4 or 5). Internal Relief for Type 627R or 627MR Regulator The Type 627R internal relief performance values (table 3) were obtained by removing the disk assembly from the regulator, see figure 8. For the Type 627R or 627MR regulator, the internal relief across the diaphragm (figure 5 or 6) provides overpressure protection in many applications. As outlet pressures build up above the start-to-discharge point, the diaphragm moves off the relief valve seat allowing the excess pressure to bleed out through the screened vent. For extra protection, should failure conditions exist which would prevent normal operation of the regulator (for example, disk broken off or disk erosion), the pusher post contacts the lever retainer (figure 2) causing the relief valve assembly to open. Since the diaphragm continues to rise as downstream pressure builds, it opens the relief valve, thereby opening the valve. This internal relief may be adequate for the application. Downstream Control Line for Type 627M, 627HM, or 627MR Regulator A Type 627M, 627HM, or 627MR regulator has a blocking throat stem seal with O-rings and a 1/4-inch NPT control line connection in the diaphragm case (figure 6). A regulator with a downstream control line is used for monitoring applications or other applications where other equipment is installed between the regulator and the pressure control point. The stem seal separates the body outlet pressure from the diaphragm case.

1. For inlet pressure in excess of 1000 psig (69 bar), refer to the maximum body and disk pressure ratings in the specification table. 2. For pressure settings under 10 psig (0.69 bar), inlet pressure should be limited to approximately 100 psig (6.9 bar) so the set point adjustment can be obtained.

3. The unbalance forces change from the wide open monitor mode to an active regulator mode such that the Type 627M or 627HM should have a 3/8-inch (9.5 mm) or larger seat ring when used as a wide open monitor.

Overpressure ProtectionLike most regulators, 627 Series regulators have outlet pressure ratings that are lower than their inlet pressure ratings. A pressure relieving or pressure limiting device must be provided by the user for the Type 627, 627M, and 627HM regulators if the inlet pressure can exceed the outlet pressure rating, since these regulators do not have internal relief. Type 627R regulators provide internal relief which limits the total outlet pressure buildup over setpoint. Use table 3 and the following example to determine the maximum inlet pressure allowed to keep the maximum allowable downstream pressure from being exceeded. Given: 40 psig 125 psig 1/4-inch Desired outlet pressure setting Maximum allowable downstream pressure Port diameter

less than the inlet pressure shown under the Maximum Inlet Pressure column heading in table 3. If the maximum allowable downstream system pressure is less than any of the pressures shown in the third column of table 3, use a separate relief valve or a monitor regulator since the internal relief will not open at pressures lower than shown in the table. If the actual inlet pressure is higher than the pressure shown, in the Maximum Inlet Pressure column, to protect to the level shown, an additional relief valve is needed to supplement the relief capacity of the 627R internal relief or a full capacity separate relief valve or monitor regulator may be used. To size a supplemental relief valve to use with the Type 627R: 1. Use the universal sizing equation to calculate the wide open capacity of the regulator port (Q1) using: a. Actual inlet pressure, PSIA (P1) b. Maximum allowable downstream system pressure (P2) from table 3, column 3 c. Cg from table 7 2. Use the universal sizing equation to calculate the internal relief flow (Q2) using: a. Maximum inlet pressure (P1) from table 3 columns 4 thru 9 (use the pressure from the table eventhough the actual pressure will be higher). Remember the equation requires pressures to be converted to PSIA. b. Maximum allowable downstream system pressure (P2) from table 3 c. Cg from table 7

From table 3, the maximum inlet pressure for this example is 300 psig. In many cases the internal relief of the Type 627R offers full capacity overpressure protection. No additional relief capacity is needed if the actual inlet pressure is equal to or

Capacity InformationNatural gas regulating capacities at selected inlet pressures and outlet pressure settings are given in table 4 for the Type 627, in table 5 for the Type 627H, and in table 6 for the Type 627R regulator. Flows are in scfh (60_F and 14.7 psia) of 0.6 specific gravity natural gas at 60_F. To determine the equivalent capacities for other gases, multiply the

table capacity by the following appropriate conversion factor: 0.775 for air, 0.789 for nitrogen, 0.628 for propane, or 0.548 for butane. For gases of other specific gravities, multiply the given capacity by 0.775, and divide by the square root of the appropriate specific gravity. Then, if capacity is desired in normal cubic meters per hour at 0_C and 1.01325 bar, multiply scfh by 0.0268.

1. The internal relief performance values are obtained by removing the disk assembly. 2. For inlet pressures in excess of 1000 psig (69 bar), refer to the maximum body and disk pressure ratings in the specification table. 3. For pressure setting under 10 psig (0.69 bar), inlet pressure should be limited to

approximately 100 psig (6.9 bar) so the set point adjustment can be obtained. Shaded areas indicate maximum inlet pressures allowed during system malfunction only. Table 1 gives the maximum inlet pressure for normal regulator operation.

To determine wide-open flow capacities for relief sizing use the following formula:

G = Gas specific gravity (air = 1.0) P1 = Valve inlet pressure, psia P = Pressure drop across valve, psi Q = Gas flow rate, scfh T = Absolute temperature of gas at inlet, degree Rankine

where: C1 = Cg/Cv (see table 7) Cg = Gas sizing coefficient (see table 7) To obtain the published capacities, the inlet and outlet piping should be the same as the regulator size.

1. Capacity is based on 20 percent droop unless otherwise noted below. See capacity information for conversion to equivalent capacities of other gases and/or normal m3/hr. 2. For pressure setting under 10 psig (0.69 bar), inlet pressure should be limited to approximately 100 psig (6.9 bar) so the set point adjustment can be obtained. 3. For 5 psig (0.34 bar) pressure set point the droop is 2 psig (0.14 bar). Shaded areas indicate where capacities are based on 25 percent boost if setting is less than 12 psig (0.8 bar), 3 psig (0.2 bar) boost if setting is from 12 to 60 psig

(0.2 to 4 bar), and 5 percent boost if setting is greater than 60 psig (4 bar). Shaded area shows where a Type 627MR regulator should not be used because unbalanced forces can cause the internal relief valve to start to discharge during normal operation. Refer to table 1. Shaded areas show where maximum operating inlet pressure for a given port diameter is exceeded for Type 627, 627M and 627MR regulators.

Type 627M or 627HM De-Icer System ApplicationA 627 Series regulator can be used in a de-icer application as shown in figure 9. As the seat ring in the working regulator begins to freeze, ice formation decreases the seat ring port diameter so that the working regulator is unable to supply enough flow to satisfy the downstream demand. When downstream pressure falls below the outlet pressure setting of the Type 627M regulator, the disk of the Type 627M

regulator moves off its seat ring and lets alcohol flow into the main gas line. The alcohol carried to the working regulator by the flow stream helps prevent additional ice formation on the seat ring. Normal flow then resumes, and as pressure in the downstream system is restored, the Type 627M regulator shuts off. This is an economy feature which conserves both the alcohol and the number of manhours required to maintain the alcohol supply. The alcohol is supplied to the working regulator only when icing conditions exist.

1. Capacities are based on 20 percent droop. See capacity information for conversion of equivalent capacities of other gases and/or normal m3/hr. 2. For pressure setting under 10 psig (0.69 bar), inlet pressure should be limited to

approximately 100 psig (6.9 bar) so the set point adjustment can be obtained. Shaded areas show where maximum operating inlet pressure for a given port diameter is exceeded for a Type 627R regulator.
