Pressure regulating valve e.g.for driving directional control valves and hydraulic cylinders in furniture and vehicles engineering

摘要

An electromagnetically controlled hydraulic pressure regulating valve has a control spool (piston) 2 moved to regulate the flow path between a supply port P, an outlet port A and a return to tank port T. The spool is moved by the armature 5 of an electromagnetic actuator 6 that has a coil 8. The armature is mechanically coupled to the piston 17 of a viscous friction damper that is supplied 21 with fluid from the output port of the pressure regulating stage.
