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 setting, the direct-acting relief function is activated and flow is relieved from C2 to V2. With pilot pressure at Pil, the pressure setting is reduced in proportion to the stated ratio, until opening and allowing flow from C2 to V2. The spring chamber is drained to V2. The valve applies a balanced piston allowing relief 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.
Note: for applications outside these parameters, please consult us.
