Model 2RJV1-06 are pilot operated check valves in a
sandwich plate design used to give leakfree closure of
one or two actuator ports under pressure, even during
long idle periods.
The valve consists of the cast iron housing (1), one or two
check valves (2), (3) and the pilot piston (4).
When fluid flows from A1 (B1) to A2 (B2) it opens the
check valve (2), (3) and at the same time shifts the pilot
piston (4) to the right (left), thus opening the way B2 ® B1
(A2 ® A1). When the pressure drops (i. e. after shifting
the directional valve into its middle position), the springs
push the poppets onto the seats and the circuit between
the check valve and the cylinder is closed.
To ensure that the poppet valves seat properly, the
actuator ports A2 and B2 of the directional valve should
be connected to tank T in neutral position (functional
symbol Y).
The valve body is phosphate coated, the surfaces of the
other parts are zinc coated.
