H & HC Type Pressure Control Valve

These valves are hydraulically damped, direct operated, pressure control valves which can be actuated by internal or external pilot pressure. There are various types of valve including sequence, unloading and low pressure relief valves, all of which are operated by a pressure rise in the circuit, sensed either internally or remotely.

Features / specifications

Note: Model with auxiliary pilots are used where valves must be operated under a lower external pilot pressure than the adjusted pressure (types N, A and B about 1/8 of adjusted pressure; type C: about 1/16). This does not apply to pressure adjustment ranges L and M, and valve type 1.
To adjust the pressure, loosen the lock nut and turn the pressure adjustment screw slowly clockwise to increase pressure or anti-clockwise to decrease pressure. After adjustments, do not forget to tighten the lock nut.
