The directional control valve type PX-348 is designed to control the direction of the working liquid flow between the generators of pressurized flow (hydraulic pumps), consumers of such a flow (hydraulic cylinders, etc.) and the tank.
The directional control valve is a section type with manual operation.It provides parallel distribution of the working liquid and directs flow to the tank at non-actuated sections.It comprises a front cover with build-in adjustable or non-adjustable pressure relief valve, a combination of single-acting(valve or spool) and double acting(spool) three-position sections (maximum eight numbers) and end cover.
The directional control valve is mounted by four bolts M8.To the pipelines of the hydraulic system by means of threaded outlets M18x1.5/3.8"/
