Single counterbalance,
relief compensated
When pressure at V2 rises above the spring bias pressure, the check seat is
pushed away from the piston and flow is allowed from V2 to C2. When load
pressure at C2 rises above the pressure setting, flow is relieved from C2 to V2.
With pilot pressure at V1–C1, the pressure setting is reduced in proportion to
the stated ratio of the valve, until opening and allowing flow from C2 to V2. The
spring chamber is drained to V2. The valve applies a balanced piston and relief
is operated at the valve setting independent of back-pressure at V2. However,
the piloted opening of the valve remains subject to additive pressure at port V2.
For safety and compactness, the C2 port is gasket mounted the actuator.
Note: port identified with M are not protected with calibrated orifice but in
direct connection with pressure channels.
