Product Description

Bucher WR22G-EZ5-5 Directional Control Valve

The Bucher WR22G-EZ5-5 is a high-performance, direct solenoid-operated directional spool valve. It is designed according to the NG10 (CETOP 5 / NFPA D05) standard interface, ensuring interchangeability. This valve features two solenoids for 3-position control and is spring-centered. The ‘EZ5’ spool configuration typically indicates a closed-center type where ports P, T, A, and B are blocked in the neutral position. It is commonly used in industrial and mobile hydraulic systems to control the direction of fluid flow, enabling the actuation of cylinders or hydraulic motors.
