PSV1-16 - Pressure Sequence Valve
Spool, pilot operated, normally closed, internal pilot, external drain
95 L/min (25 USgpm) • 350 bar (5000 psi)
Operation
In the normal condition port 2
is open to the tank port 3 and
port 1 is blocked.
When the pressure on port
1 exceeds the setting of the
valve port 1 opens to port 2
and port 3 is blocked but must
always be referenced to tank.
Features
Hardened steel working parts
give long, trouble-free life.
Selectively matched honed
assemblies give accurate
performance.
