F63-PPR PRESSURE REDUCING VALVE

Fig No.: F6316-PPR (PN16) / F6325-PPR (PN25)

FEATURES & SPECIFICATIONS

Automatic reduces the higher inlet pressure to a steady lower downstream pressure, regardless of fluctuating demand or varying upstream pressure.
Pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. The main valve and pilot valve will close when the downstream pressure exceeds the setting of the control pilot.
Full bore globe pattern design for superior control characteristic.
Nylon reinforced diaphragm for long-lasting performance.
Durable fusion bonded epoxy coated.
Flange drilled to EN 1092-2 PN16 / EN 1092-2 PN25 / ANSI Class 150.
Design comply with EN 1074-5.
