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.
