Description

The directional control valve is designed for starting,stopping and handling the working liquid flow between the generators of pressurized flow(hydraulic pumps), the consumers of such a flow(hydraulic cyllinders and s.o) and the tank, in the hydraulic systems of mobile machines.

Construction

The directional control valve is monoblock type, manually operated,allowing two variants of working liquid distribution -parallel and serial.The charging line of each spool is equipped with check valve, preventing against return of working liquid in case of pump or motor accidental stopping.The directional control valve can be equipped with end fitting of high pressure(CARRY OVER).

Mounting

The directional control valve is mounted to its proper place by means of three securing bolts M10.The connection is performed by threaded outlets P,A,B,T and N.
