PRV1-10 - Pressure Reducing/Relieving Valve
Spool, direct acting
15 L/min (4 USgpm) • 165 bar (2400 psi)
Operation
Normally open, the valve
throttles or closes to maintain
constant pressure in the
regulated line.
As in the other direct acting
valves, the spring force holds
the valve open.
Features
Hardened steel working parts
are individually match ground to
assure long life, reliability and
high accuracy.
Performance DataSectional View
Description
This is a direct acting, screw
in cartridge pressure reducing
valve designed to provide an
adjustable regulated pressure
which is lower than supply
pressure.. Direct acting
models are suited to lower
flow applications and regulated
pressures to 165 bar (2500
psi). This valve also acts as
a relief valve, relieving from
regulated line to tank if shock
or surge pressures occur in
the regulated line.
