Description

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.


Construction

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.


Mounting

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"/
