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.
