Spirax Sarco 71431, 25P Pilot Operated Pressure Reducing Main Valve, 1-1/2 in, FNPT End Style, 300 psig, 450 deg F
CBPN: 222366
MPN:71431
DESCRIPTION
Spirax Sarco Pressure Reducing Main Valve, Pilot Operated, 1-1/2 in Nominal, NPT, 300 psig, 450 deg F, Cast Steel Body, Media: Steam, 19-3/4 in H
The 25P is a self-actuated pilot-operated pressure regulator. Downstream pressure is fed back through an external sensing line to the pressure pilot, which adjusts the opening of the main valve so as to maintain the set pressure. The main valve can close tight for ANSI/FCI 70-2 Class IV shut off when steam is not required.
