1PS200 - Pressure Sequence Valve
Spool, pilot operated, normally closed, internal pilot, external drain
250 L/min (60 USgpm) • 350 bar (5000 psi)
Description
Pilot operated models are best
suited for higher flows which
may vary widely to:
1. Provide ordered or sequenced
series of operations as in a
clamp and drill circuit.
2. Serve as a relief valve where
oil viscosity or restrictions
in the downstream line
would cause excessive back
pressure. The separate spring
chamber drain makes the
sequence valve insensitive to
this back pressure.
Operation
As in the pilot operated relief,
when the setting of the valve
is exceeded the pilot section
opens.
This pilot flow causes a pressure
imbalance opening the main
section and allowing flow to a
secondary circuit (sequenced
line).
Features
Hardened steel working parts
give long, trouble-free life.
Selectively matched honed
assemblies give accurate
performance.
