Description

A flanged pressure reducing valve designed to automatically regulate and reduce incoming high pressure to a stable downstream pressure level. The body is cast iron with a ductile iron disc and EPDM diaphragm, incorporating a brass pilot valve and needle valve assembly. Suitable for above-ground and underground installations in municipal water networks, building services, and industrial processing systems.

Selection notes

This pressure reducing valve is a pilot-operated and diaphragm type pattern, supplied for flanged installation.

Sizes run DN50 to DN800, in PN10, PN16.

The body is CI.

Seat and trim options are Brass and EPDM. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.

Stated service media include water.

It is catalogued for Water & Wastewater and HVAC.

Built to ANSI B16.10, BS 5152 and JIS Working.
