Flanged, Internally Piloted, Piston Operated, Pressure Reducing Valve – GP-1000 FF Series

The GP-1000 FF Series valves are pilot-controlled for accurate regulation of pressure under wide-ranging flow. Internal pilot design eliminates external components and piping.

Internally piloted GP Series valves are capable of larger capacity and greater accuracy than direct acting valves.

Completely supported by piping, lightweight GP Series valves install easily with NPT or flanged connections.

A stainless steel diaphragm, hardened stainless steel working parts and integral removable strainer team up to provide high performance over a long, trouble-free service life.

Valves are equipped with a single seated main valve, piston valve rings for longer life and an external adjusting screw with locking nut. All working parts are renewable in-line. ANSI Class IV Shutoff.
