Product Overview
The Rexroth Z4WEH10X183-50/4KEG24ETK4 (Material Number: R900763298) is a high-performance electro-hydraulic directional spool valve from the renowned Rexroth WEH series. This valve is designed for controlling the start, stop, and direction of fluid flow in hydraulic systems, utilizing a pilot-operated solenoid actuation mechanism. It features a size 10 (NG10) interface and a 4-way, 3-position spool configuration with a “K” type spool (open center in neutral). The integrated electro-hydraulic piloting allows for high flow rates with minimal solenoid power, making it ideal for demanding industrial applications requiring precise directional control and reliable switching under high pressure.
