The M-3SED6UK1X/350CG24N9K4/B22 valve belongs to the M-SED Poppet Valves series from Bosch Rexroth and switches hydraulic flow in automated machinery. It employs a 3/2-way normally open circuit function so pressure is released when the solenoid is de-energized. Three main ports provide connection for supply, actuator, and return lines. A wet-pin detachable coil solenoid allows quick replacement without draining the manifold. The coil is rated for a nominal 24 V DC input, and operation remains stable within a ±10 % voltage window. Continuous energizing is permissible because the duty cycle is 100 %. Power consumption is 30 W and electrical termination uses a DIN EN 175301-803 connector. With the connector fitted, the housing achieves IP65 protection against dust and water.

The valve body withstands a maximum operating pressure of 350 bar, enabling control of high-pressure mineral oil classified as HL or HLP. A concealed manual override lets technicians shift the valve poppet during commissioning or in the event of power loss. The unit can switch up to 15 000 cycles per hour, supporting rapid machine sequences, and a 2.2 mm throttle insert can be added to moderate flow and cushion shifts. Hydraulic cleanliness must reach ISO 4406 class 20/18/15 to protect sealing surfaces and maintain reliability. Coil insulation tolerates temperatures up to 150 °C, preventing thermal damage during continuous or high-frequency operation. These parameters make the valve suitable for compact, high-cycle hydraulic automation tasks.
