Type 310A-32A Pressure Reducing Regulator and Type 310A-32A-32A Working Monitor Regulator

Introduction

The Type 310A pilot-operated high-pressure regulator (Figure 1) is used where high capacity and accurate control are essential. This regulator includes one Type 32A pilot assembly mounted on the main valve for pressure reducing or wide-open monitoring applications, or two Type 32A pilots mounted on the main valve for working monitor applications.

Features

• Accurate Control—Molded pilot diaphragms provide a narrow proportional band and registration of outlet pressure on the main diaphragm allows excellent control sensitivity.

• Tight Shutoff—Throttling-sleeve design with

Polytetrauoroethylene (PTFE) seat in the body

ensures positive shutoff.

• High Capacity—Straight-through ow passage allows exceptionally high capacities and stable operation.

• Reduced Relief Requirements—Optional restricted trim helps reduce relief valve size requirements; the regulator is easily converted to full capacity by

changing the trim, if ow conditions increase.

• Fast Speed of Response—Designed to meet stringent speed of response requirements for turbine startup and fuel gas applications.

• Minimum Installation Space Required—Since main valve design incorporates actuator spring, less installation space is needed for the Type 310A than for other regulators of comparable capacity.

MAIN VALVE SPRING

Principle of Operation

Single-Pilot Regulator (Figure 2)

The regulator inlet pressure enters the pilot through the external pilot supply line and is utilized as the supply pressure for the pilot. The setting of the pilot control spring determines the reduced outlet (downstream) pressure.

In operation, assume the outlet pressure is less than

the setting of the pilot control spring. Pilot control spring force then overcomes the force resulting from outlet pressure acting on the bottom diaphragm. The spring pushes the diaphragm plate and yoke assembly away from the relay seat, opening it and supplying additional loading pressure to the main valve diaphragm. When this additional loading pressure exceeds the force resulting from outlet pressure acting on the main valve diaphragm plus

STATIONARY VALVE PLUG

the force of the main valve spring, the diaphragm is pushed away from the stationary valve plug. The throttling sleeve opens wider, and the required gas is supplied to the downstream system.

When gas demand in the downstream system has

been satisﬁed, the outlet pressure tends to increase.

The increased outlet pressure acting on the bottom diaphragm of the diaphragm plate and yoke assembly results in a force that overcomes the pilot spring setting and forces the assembly toward the relay seat, closing it. The loading pressure acting on the main valve diaphragm bleeds to the downstream

system through the ﬁxed restriction in the diaphragm

plate and yoke assembly. When rapid main valve closure is required by unusual control conditions, the bleed valve opens for increased bleed rate. The force of increased outlet pressure acting on the main valve diaphragm plus the main valve spring force overcomes the force of decreased loading pressure acting on the main valve diaphragm and moves the

throttling sleeve toward the stationary valve plug to

decrease the gas ow to the downstream system.

The top diaphragm in the pilot acts as a sealing member for the loading chamber and as a balancing member to the bottom diaphragm. The two diaphragms are connected by a yoke. Pressure change to the center chamber has little effect on the positioning of the valve disk.

Monitor Systems

Wide-Open Monitors (Figure 3)

Monitoring regulators serve as overpressure protection devices to limit system pressure in the event of failure of working regulators feeding the system. The control line of a wide-open monitoring regulator may be connected downstream of the working regulator, so that during normal operation the wide-open monitoring regulator is standing wide open with the pressure reduction being taken across the working regulator. Only in case of working regulator failure does the wide-open monitoring regulator operate.

E0695

of the Type 32A monitoring pilot. A plug in both the working and monitoring pilots makes the internal bleed nonfunctional. A restriction placed in the external tubing between the diaphragm loading pressure and the intermediate pressure acts as a downstream bleed.

If the second-stage working regulator fails to open,

the distribution pressure increases to the setting of the Type 32A monitoring pilot (slightly higher than the original distribution pressure) and is controlled at that level by the Type 310A-32A-32A. Thus, downstream equipment is protected against a major overpressure condition without disrupting service or venting gas to atmosphere.

In the working pilot, the inlet pressure is reduced

to a pre-determined pilot supply pressure, which is further reduced to loading pressure for the Type 310A diaphragm. The loading pressure is piped through the portion of the monitoring pilot blocked open by the spacer and, as long as distribution pressure is below the setting of the monitoring pilot, passes through the

relay oriﬁce of the monitoring pilot to the diaphragm

case of the Type 310A body.

Working Monitors (Figures 4 and 5)

The Type 310A-32A-32A working monitor regulator differs from wide-open monitors in that it has working monitor capability. This means that it normally reduces pressure and throttles while the second-stage regulator is in operation. Should the second-stage working regulator fail open, the Type 310A-32A-32A will take over the entire pressure reduction function.

The working monitor pilots are adaptations of two Type 32A pilots with special internal parts, due to the pressure conditions in this piloting system. A spacer blocks open the differential regulator portion

Distribution pressure is piped back to the monitoring pilot. As long as the distribution pressure is less than the monitoring pilot setting, the working pilot controls

the Type 310A to maintain intermediate pressure. If

the distribution pressure increases to the monitoring

pilot setting, the monitoring pilot relay oriﬁce starts

to throttle the loading pressure to the Type 310A diaphragm. This allows the Type 310A main spring to move the throttling sleeve closer to the seat and control distribution pressure at the monitoring pilot set point. Therefore, failure of the second-stage working regulator is controlled with only a slight increase in distribution pressure, with the Type 310A-32A-32A accomplishing the entire pressure reduction function.

Capacity Information

Note

Type 310A regulator flow capacities are laboratory verified; therefore, they may be sized for 100% flow using capacities as shown in Tables 8, 9, 10, 11, and 12. It is not necessary to reduce published capacities.

Tables 8, 9, 10, 11, and 12 show the natural gas regulating capacities of the Type 310A regulator at selected inlet pressures and outlet pressure settings. Flows are in thousands of SCFH at 60°F and 14.7 psia (and in thousands of Nm3/h at 0°C and 1,01325 bar) of

0.6 speciﬁc gravity natural gas.

To determine equivalent capacities for air, propane, butane, or nitrogen, multiply the capacity by the following appropriate conversion factor: 0.775 for air, 0.628 for propane, 0.548 for butane, or 0.789

for nitrogen. 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.

To ﬁnd approximate regulating capacities at pressure

settings not given in Tables 8, 9, 10, 11, and 12 or

to ﬁnd wide-open ow capacities for relief sizing

at any inlet pressure, perform one of the following procedures. Then, if necessary, convert using the factors provided above.

For critical pressure drops (absolute outlet pressure equal to or less than one-half of absolute inlet pressure), use the following formula:

Q = (P1)(Cg)(1.29)

For pressure drops lower than critical (absolute outlet pressure greater than one-half of absolute inlet pressure).
