Excess Flow Prevention Valves
Premier Excess Flow Prevention Valves are unique factory adjustable gas valves designed to automatically shut off the flow of gas when flow exceeds a preset level. These valves are designed to protect systems and/or people in the event of a line failure down the stream from a valve.
Premier excess flow valves are available in three unique designs. The miniature EFPV operates on systems between 30 and 200 PSIG (2.07 and 13.79 bar), offering a wide range of factory adjustable trip points. The high pressure EFPV_HP includes all the features of the EFPV with an increased maximum pressure up to 3000 PSIG (172.37 bar). The high sensitivity EFPV_HS valve is ten times more sensitive than the EFPV with an extended low range system pressure down to 5 PSIG and the lowest settable trip-point of the three valves.
Flow rates can be preset at the factory location to meet customer specifications. After a valve has tripped it can be reset with a convenient integrated bypass valve or reset slider that will allow users to quickly get their systems back up and running (after repairing the leak which caused the valve to trip). Premier Excess Flow Valves are remarkably flexible with a variety of available construction materials, multiple porting configurations, a wide range of operating pressures and factory adjustable trip points.
