The WH 25 E,F,J,H,G,U series of 4/3-, 4/2- and 3/2-way Rexroth WH25 high flow CETOP porting pattern hydraulic directional spool valve is used to control the direction, start by hydraulic force, the hydraulic control valves we produced have the characteristic of low switching noise, great performance, replacement and standard mounting.
4/3-, 4/2- and 3/2-way Rexroth WH25 High Flow CETOP Porting Pattern Hydraulic Directional Spool Valve
4/3-, 4/2- and 3/2-way Rexroth WH25 High Flow CETOP Porting Pattern Hydraulic Directional Spool Valve
The operation principle of Rexroth WH valve:
1.When there is no pressure oil in the X, Y two ports the spring spool in centering, the functional symbols is centering position, the port of A, B , P , T mutually disconnection , the cylinder is not movement.
2.When the the X port flows into pressure control oil, the spool is switched to the right position by compressing spring, the function symbols left. The port of P and B, A and T are connected. The oil is drained to the oil tank by port Y and the cylinder moves to left.
3.When the the Y port flows into pressure control oil, the spool is switched to the left position by compressing spring, the function symbols right. The port of P and A, B and T are connected. The oil is drained to the oil tank by port X and the cylinder moves to right.
