Model RJV1-05 are pilot operated check valves in
cartridge design used to give leakfree closure of a
hydraulic actuator port under pressure, even during
long idle periods.
They basically consist of housing (1), check valve (2),
and pilot piston (3). The cartridge is avaliable alredy
assembled into a subplate for direct mounting onto the
actuator (page 4 of this data sheet).
When fluid flows from port 2 ® 3, it opens the check
valve automatically. When the pressure in port 2 drops
(e.g. after shifting the directional valve into its middle
position), the spring pushes the ball (2) onto the seat
and the circuit between the check valve and the actuator
is closed. The control pressure (port 1) acting on the
pilot piston (3) moves the ball (2) from the seat and
makes the flow passage 3 ® 2 free. An additional port 4
is available for use in double acting applications using
two pilot operated check valves-see typical circuits
(page 3) and drawings (page 5).
The valve body is blackened. The hollow bolt and the
surface of the subplate are phosphate coated.

Hydraulic circuit with two pilot operated check
valves enabling movement in both directions.
The use of a directional valve with Y-functional
symbol ensures perfect seating of the ball,
thus ensuring tight closure of the actuator.
Use of the pilot operated check
valve for one direction only
(lowering). Port 4 is pluged
