Description:

Rexroth Solenoid Valve Blue 4WE6H62/EW230N9K4 is a high-performance solenoid directional valve manufactured by Bosch Rexroth, Germany. The solenoid valve belongs to the WE6 series and is a direct acting 4/2-way solenoid valve with cast iron housing and NBR (Nitrile Butadiene Rubber) sealing material. It is designed to meet international standards such as DIN 24340-A6, ISO 4401-03, CETOP R 35 H-03 and NFPA-D03.
The operating principle of this solenoid valve is to control the movement of the spool by energizing and de-energizing the solenoid coil, thus changing the flow direction of the hydraulic fluid. In the initial position, hydraulic fluid flows from port P to port A, and from port B to port T. The valve is designed to be used in a wide range of applications. When the solenoid coil is energized, the spool moves so that the P port is connected to the B port and the A port is connected to the T port. In addition, the solenoid valve is equipped with a manual reset function, which can be operated manually in case of power failure.
