High Pressure, Excess Flow Prevention Valve
The Premier High Pressure Excess Flow Valve (EFPV_HP) is part of a family of unique factory adjustable gas valves designed to automatically shut off the flow of gas when flow exceeds a preset level. The valves are designed to protect systems and/or people in the event of a line failure down the stream from a valve. The Premier EFPV_HP can be positioned in line with a maximum pressure up to 2500 PSI. Flow rates can be preset at the factory location to meet customer specifications.
The EFPV_HP relies upon a change in internal pressure across a piston when flow increases to trip the valve. After a valve has tripped it can be reset with a convenient integrated bypass valve that will allow users to quickly get their systems back up and running after repairing the leak which cause the EFPV_HP to trip. The variety of available construction materials and porting configurations as well as the wide operating pressure range and factory adjustable trip point makes the EFPV_HP a remarkably flexible valve.
