Functions and features
1. Compact size, light and handy structure, small weight, simple operation and safety & reliability;
2. Work group number can be added according to demand, 7 spools at most.
3. Complete configuration of primary and secondary overflow valves; Opening pressure to be adjusted as required by customers;
4. Series-parallel connection structure and external load retaining valve ensure that the actuating mechanism with higher load will not fall in operation.
5. Modules with different functions on the valve group can realize the switchover between single and dual pumps to improve working efficiency and save energy consumption.
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.
