Rexroth WH16 fluidic actuation hydraulic directional spool valve are the industrial standard valve with NFPA porting pattern, the main function is the hydraulic force pushes the spool forwarder and reverse direction.
Rexroth WH16 Fluidic Actuation Hydraulic NFPA Porting Pattern Directional Spool Valve
The operation principle of WH Hydraulic directional control 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.
