Type 310A fuel pressure regulator is used for high-pressure applications which require fast response such as fuel gas supply to a gas turbine or other large volume applications. The Type 310A fuel pressure regulator includes one Type 32A pilot assembly mounted on the main valve for pressure reducing or wide-open monitoring applications. Type 310A fuel pressure regulator has accurate control, tight shutoff, high capacity, and fast speed of response.

High Capacity—The highly efficient axial flow design produces exceptionally high capacities.
Tight Shutoff—Throttling-sleeve design with Polytetrafluoroethylene (PTFE) seat in the body ensures positive shutoff.
Accurate Control—Molded pilot diaphragms provide a narrow proportional band and registration of outlet pressure on the main diaphragm allows excellent control sensitivity.
Fast Speed of Response—Designed to meet stringent speed of response requirements for turbine startup and fuel gas applications.
Absolutely No Atmospheric Bleed—Eliminates nuisance and wasteful bleed gas to atmosphere by utilizing a pilot-operated control system, which bleeds 100% of the gas to the downstream system.
High Turn Down Capability—The oversized diaphragm and unique piloting system allow for high turn down, providing superior pressure control in systems with large variations in downstream flow demand.
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.
Long Life in Severe Service Application—The metal plug design deflects particles and debris away from the soft-seat, which gives excellent particle erosion resistance, prolonging service life.
