4WE6G6X/EW110N9K4/ZV

The 4WE6G6X/EW110N9K4/ZV valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation where electrically operated spool shifting directs pressure and return flow. It conforms to Size 6 (NG6), making it suitable for compact manifold installations. The porting pattern follows ISO 4401-03-02-0-05 so the mounting face lines up with standard subplates without adaptation plates. A maximum operating pressure of 350 bar allows use in high-pressure circuits, while the valve passes up to 60 l/min (AC) to support medium-flow actuators. The tank port tolerates 160 bar (AC), preventing seal damage when return pressure rises. Switch-on power is 220 VA, defining the inrush demand placed on the control transformer, and once the spool has shifted the required holding power falls to 50 VA to reduce heat generation. A duty cycle of 100 % ED permits the solenoid to remain energized continuously during extended machine cycles.

Electrical and mechanical features help integrate the valve into control cabinets and field blocks. It operates on a nominal voltage of 110 V at 50 / 60 Hz so it can connect directly to common industrial control supplies. The K4 connector defined by DIN EN 175301-803 provides a plug-in interface that speeds wiring and maintenance. With that connector in place, the enclosure attains protection class IP65, keeping out dust and low-pressure water spray. Coil surface temperature may reach 120 °C under continuous duty, so adjacent components must tolerate elevated heat. A maximum switching frequency of two cycles per second (AC) dictates the highest rate at which directional commands can be issued. The clamping length is 22 mm, specifying how far the body seats into the retaining bolts to ensure leak-free compression of the subplate seal. FKM seals are used to resist hot hydraulic oil and maintain long service life under the valve’s rated temperatures and pressures.
