627 Series Pressure Reducing Regulators

Introduction

The 627 Series direct-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

Specications section).

Features

• Internal Relief Valve—Types 627R, 627LR, 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 Specications

section for performance data.

March 2013

• Types 627R, 627LR, and 627MR Travel Stop— The internal relief valve still works if the disk or linkage fails. The pusher post (Figure 6) contacts the travel stop of the lever retainer and, as the diaphragm continues to rise, it opens the relief valve.

• Relief Operation Indicator—A rubber cap (Figure 7) slipped on the vent assembly pops off when the relief valve opens, indicating the relief valve has opened since the last inspection.

• Easy to Maintain—Trim parts can be replaced without removing the regulator body from the pipeline. A two-bolt connection between the body and diaphragm

casing simplies disassembly for maintenance.

• Installation Adaptability—The diaphragm case and/ or regulator body can be rotated in any of four positions to allow regulator installation in locations with limited space (Figure 8). The regulator may be installed in any position without affecting operation as long as the spring case vent is protected from the elements.

• Application Versatility—The different 627 Series constructions can be used as farm tap regulators, regulator-relief valves, monitoring regulators, or high-pressure industrial regulators.

• Extended Body Option—The Type 627 Long Body is available with same face-to-face dimensions as the Type 630 with threaded NPT end connections.

• Tamper-Resistant—An adjusting screw locknut and protective cap (Figure 2) is standard on all 627 Series regulators to discourage tampering with the pressure setting.

• Wide Range of Flow Capabilities—A selection of

body sizes and orice sizes is available to satisfy various ow requirements.

• Tight Shutoff Capability—A at-faced disk of Nitrile (NBR), Nylon (PA), or Fluorocarbon (FKM) provides excellent shut-off capability.

Principle of Operation

Refer to Figures 2 through 5. When downstream demand decreases, the pressure under the diaphragm increases. This pressure overcomes the regulator setting (which is set by a spring). Through the action of the pusher post assembly, lever, and valve stem the valve disk moves

closer to the orice and reduces gas ow. If demand

downstream increases, pressure under the diaphragm decreases. Spring force pushes the pusher post assembly downward and the valve disk moves away from

the orice allowing more ow through the body to the

downstream system.

Product Description

Types 627 and 627H Direct-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 Tables 6 through 12).

Type 627 Long Body

the Type 627R, 627LR, or 627MR regulator, the internal relief across the diaphragm (Figure 3 or 4) 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 6) 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 NPT control line connection in the diaphragm case (Figure 4). 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.

The Type 627 Long Body regulator can be used as a drop-in replacement for existing Type 630 installations without the need to modify piping.

Internal Relief for Type 627R, 627LR, or 627MR Regulator

The Types 627R and 627LR internal relief performance values (Tables 4 and 5) were obtained by removing the

disk assembly from the regulator, see Figure 9. For

Installation

Regulator operation within ratings does not preclude the possibility of damage from debris in the lines or from external sources. A regulator should be inspected for damage periodically and after any overpressure condition. Ensure that the operating temperature capabilities listed in

Specications section are not exceeded.

Overpressure Protection

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 Types 627, 627H, 627M, and 627HM regulators if the inlet pressure can exceed the outlet pressure rating, since these regulators do not have internal relief.

Types 627R and 627LR regulators provide internal relief which limits the total outlet pressure build-up over setpoint. Use Table 4 or 5 and the following example to determine the maximum inlet pressure allowed to keep the maximum allowable downstream pressure from being exceeded.

Given:

Desired outlet pressure setting : 40 psig / 2.8 bar Maximum allowable

downstream pressure

: 125 psig / 8.6 bar

From Table 4, the maximum inlet pressure for this example is 300 psig / 20.7 bar.

In many cases the internal relief of Types 627R and 627LR offers full capacity overpressure protection. No additional relief capacity is needed if the actual inlet pressure is equal to or less than the inlet pressure shown under the Maximum Inlet Pressure column heading in Tables 4 and 5.

If the maximum allowable downstream system pressure is less than any of the pressures shown in the third column

1. For inlet pressure in excess of 1000 psig / 69.0 bar, refer to the maximum body and disk pressure ratings in the Specications section.

2. For pressure settings under 10 psig / 0.69 bar, inlet pressure should be limited to approximately 100 psig / 6.9 bar so the setpoint 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 orice.

of Tables 4 and 5, 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 Type 627R or 627LR 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 or 627LR:

Q supplemental relief = 20 300 – 13 200 = 7100 SCFH / 544 - 354 = 190 Nm3/h

Overpressurizing any portion of a regulator or associated equipment may cause personal injury, leakage, or property damage due to bursting of pressure-containing parts or explosion of accumulated gas.

If needed, provide appropriate pressure-relieving or pressure-limiting devices to ensure that none of the

speci cations are exceeded. Regulator operation within

ratings does not prevent the possibility of damage from external sources such as debris in the pipeline.

Refer to the relief sizing coef cients in Table 15 and the

Capacity Information section to determine the required external relief valve capacity.

Capacity Information

Natural gas regulating capacities at selected inlet pressures and outlet pressure settings are given in Tables 6 to 9 for the Type 627 or 627M, in Tables 10 to 12 for the Type 627H, and in Tables 13 to 14 for the Type 627R regulators. Flows are in SCFH (60°F and

14.7 psia) and Nm3/h (0°C and 1.01325 bar) of 0.6

specic gravity natural gas.

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

specic gravities, multiply the given capacity by 0.775, and divide by the square root of the appropriate specic gravity.

Then, if capacity is desired in Nm3/h at 0°C and

1.01325 bar, multiply the values in SCFH by 0.0268.

To determine wide-open ow capacities for relief sizing

use the following formula:

where,

Q = gas ow rate, SCFH G = specic gravity of the gas

T = absolute temperature of gas at inlet, °Rankine Cg = gas sizing coefcient P1 = absolute inlet pressure, psia C1 = ow coefcient (Cg ÷ Cv) P = pressure drop across the regulator, psi

To obtain the published capacities, the inlet and outlet piping should be the same as the regulator size.

1. The internal relief performance values are obtained by removing the disk assembly.

2. For inlet pressures in excess of 1000 psig / 69.0 bar, refer to the maximum body and disk pressure ratings in the Specications section.

3. For pressure settings under 10 psig / 0.69 bar, inlet pressure should be limited to approximately 100 psig / 6.9 bar so the setpoint 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.

Type 627M or 627HM De-Icer System Application

A 627 Series regulator can be used in a de-icer

application as shown in Figure 10. As the orice in

the working regulator begins to freeze, ice formation

decreases the orice size so that the working regulator is unable to supply enough ow 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 orice and lets alcohol ow into the main gas line. The alcohol

carried to the working regulator by the ow stream helps prevent additional ice formation on the orice. Normal ow 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 man hours required to maintain the alcohol supply. The alcohol is supplied to the working regulator only when icing conditions exist.
