40L/Min Monoblock Hydraulic Directional Control Valve for
P40 series valves with middle-high pressure monoblock construction
is developed based on Europe
1. Inner check valve: The check valve inside the valve body is to
insure the hydraulic oil not to be
2. Inner relief valve: The relief valve inside the valve body is
able to adjust the hydraulic system working
3. Oil way: Parallel circuit, power beyond option
4. Control Way: Manual control, pneumatic control, hydraulic and
electric control for optional.
5. Valve construction: monoblock construction, 1-7 levers.
6. Spool Function: O,Y, P,A.
7. Option: Hydraulic lock is available to be added on A and B port.
8. Available with manual, pneumatic control, electric and pneumatic
control, hydraulic and electric
control and etc.
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
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.
This product is applicable to special vehicles like truck mounted
crane, wrecker, scrubbing machine and dynamic compactor and can
effectively control such actuating mechanisms like motor and oil
