1PSC100 - Pressure Sequence Valve
Poppet, pilot operated, normally closed, internal pilot, external drain, reverse flow check
150 L/min (40 USgpm) • 350 bar (5000 psi)
Description
Sequence valves provide
ordered sequencing of two
or more operations as with
clamp and drill circuits. They
can also be used as relief
valves where the downstream
pressure is high or changes
during operation. By taking the
drain line directly to tank, back
pressure effects are negated.
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
Match ground and honed
hardened working parts
give long, trouble-free life.
Consistent stable operation
providing low pressure rise due
to increasing flow.
Cartridge construction
gives maximum flexibility in
mounting. Steel valve bodies
available on request.
