 Description
Manually or mechanically controlled hydraulic directional control valve Р40 is designed for distribution and control of work flow between generator (pump) and executive mechanisms (cylinder, hydro-motor, etc.). It is manufactured with 1 to 7 plungers, with parallel or serial action, with common or individual back valve for each plunger, with or without safety valve

Construction Р40 is a monoblock distributor. Its body is made of cast iron 30. Plungers are made of carburized steel with hard chrome plating. Mounting The distributor is fixed with 3 bolts M8
Directional control valves are one of the most fundamental parts in hydraulic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a piston inside a cylinder which is electrically controlled. The movement of the cylinder restricts or permits the flow, thus it controls the fluid flow.
Directional control valves are mainly two types:
* Hydraulic and
* Pneumatic.
Hydraulic directional control valves are for a liquid working fluid (e.g. water, hydraulic oil) and pneumatic directional control valves are for a gaseous (usually air) working fluid. |
