Product Description
This valve is a pilot to open check valve. It has a non-sealed pilot, a steel seat, and is non-
vented. It allows free flow from the valve (port 2) to the load (port 1) and blocks flow in the
opposite direction. Pressure at the pilot (port 3) will open the valve from port 1 to port 2. Pilot
pressure needed at port 3 to open the valve is directly proportional to the load pressure at port
1. Pressure at port 2 directly opposes pilot pressure.
Technical Features
Provides hose break protection,
prevents loads from drifting and
positively locks pressurized loads.
Standard unsealed pilot allows air
trapped in the pilot line to be purged
from the circuit.
Extremely low leakage. The seat and
poppet are heat treated for long life. If
the load drifts due to the valve, the seat
has probably been damaged by
contamination and the valve should be
replaced.
Optional external porting out of the hex
end of the cartridge is available for
external piloting. In this configuration,
port 3 is blocked. See Control options
E, and P.
Pilot-to-open check cartridges are
locking valves, not motion control
valves. For motion control applications,
This 3 port pilot-to-open check valve
and 3 port counterbalance valves are
physically interchangeable (i.e. same
