In the above, the structure and function characteristics of O-type, H-type, M-type and Y-type hydraulic reversing valves have been analyzed. In this paper, Dalan Hydraulics will continue to lead you to understand P-type, N-type, U-type and K-type. The functional and structural characteristics of the J-type and C-type hydraulic reversing valves.

1, P type
1Structural features: In the middle position, the oil return port T is closed, and the oil inlet port P communicates with the working oil ports A and B.
2 function features:
a. For double-rod double-acting cylinders of equal diameter, the hydraulic pressures at both ends of the piston are balanced with each other, and the working mechanism can be stopped. It can also be used in a mechanism with a hand crank. However, for a single-rod or double-acting double-acting cylinder of unequal diameter, the working mechanism cannot be in a stationary state to form a differential circuit.
b. It is relatively stable from stop to start. When the cylinder is pressurized by the two chambers, the brake is stable.
c. The hydraulic pump cannot be unloaded.
d. The change of the commutation position is smaller than that of the H type and is widely used.
2, N type
1Structural features: In the middle position, the oil inlet port P and the working oil port B are closed, and the working oil port A and the oil return port T are communicated.
2 function features:
a. The hydraulic pump cannot be unloaded.
b. It can move in one direction under the action of external force.
3, U type
1Structural features: A, B working oil port is connected, oil inlet port P, oil return port T is closed.
2 function features:
a. Since the working oil ports A and B are connected, the working device is in a floating state and can be moved under the action of an external force, and can be used for a mechanism with a hand crank device.
b. It is stable from stop to start.
c. It is also relatively stable when braking.
d. The hydraulic pump cannot be unloaded.
4, K type
1Structural features: In the middle position, the oil inlet port P communicates with the working oil port A and the oil return port T, and the other working oil port B is closed.
2 function features:
a, the hydraulic pump can be unloaded.
b. The performance is different when commutating in both directions.
5, J type
1Structural features: the oil inlet port P and the working oil port A are closed, and the other working oil port B is connected to the oil return port T.
2 function features:
a. The hydraulic pump cannot be unloaded.
b. The performance is different when commutating in both directions.
6, type C
1Structural features: the oil inlet port P is in communication with the working oil port A, and the other working oil port B is in communication with the oil return port T.
2 function features:
a, the hydraulic pump can not be unloaded;
b. It is stable from stop to start, and there is a big impact when braking.
