Product Overview
The Rexroth R901370939 is a high-performance directional seat valve engineered by Bosch Rexroth for precise control of hydraulic fluid flow direction in industrial power units. Operating on a poppet-and-seat sealing principle, this valve delivers zero-leakage shut-off in the closed position, making it ideal for load-holding and safety-critical circuits. As a direct-operated directional valve, it responds rapidly to pilot signals and ensures reliable switching performance in demanding hydraulic systems. The R901370939 is designed as a direct-fit replacement for OEM installations, offering dimensional and functional compatibility with standard Rexroth directional valve interfaces.
