These Pilot Operated Check Valves
offer a unique poppet seal design making them ideal for
pallet applications or other specialized control circuits where zero leakage is essential.
They can be used in any application where pressure must be maintained in a portion of a circuit
until a separate pilot signal opens the valve and allows free flow in the reverse direction.
The pilot pressure required to release the valves is approximately
one third of the pressure being
released. The pilot piston is sealed to prevent pilot flow through the valve.
These valves are used with StrongHold’s doubleacting manual pallet valve.
The replaceable filter elements protect the check valve and your other
system
components from contamination.
No disassembly of circuit plumbing is required to service
the filters or the check valve cartridge.
An additional filter is recommended for protection of the
return side of doubleacting clamping circuits.
