Description
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, the relief function is activated and flow is relieved from C2 to V2. With pilot pressure at V1–C1 , the pressure setting is reduced in proportion to the pilot ratio, until opening and allowing flow from C2 to V2. The spring chamber is vented to atmosphere allowing operation of all functions independent of back-pressure at V2. For better safety and compact assembly, the C1 and C2 ports are gasket mounted directly on the actuator.
Note: port identified with M are not protected with calibrated orifice but in direct connection with pressure channels.
Note: for applications outside these parameters, please consult us.
