4/3-way hydraulic valve HV4

Product description:
4/3-way valves HV4 can be used as direct actuators of small hydraulic cylinders or as pilot control valves by actuating 3/2- way valves to fill large cylinders with large volume so that hydraulic cylinders can be retracted or extended.

Functional principle:
Single-lever 4/3-way valves HV4 have three switch positions. 4/3-way valves HV4 with two separate levers have an additional switch position. When switching into one of the available positions, the hydraulic fluid flows from the pressure supply P directly via A or B or indirectly via 3/2-way valve cartridges to the actuated device. After performing the function, the fluid flows back from A or B into the tank via R.

P: pressure port
R: return port
A and B: actuator ports
