Product Overview
The Rexroth URPX-10A-20 (Material Number: R901106468) is a direct-operated pressure relief valve engineered for precise system pressure limitation and overload protection in industrial hydraulic circuits. As part of the Rexroth URPX series, this valve operates on a spring-loaded poppet principle, where a pre-set compression spring holds the poppet against the seat until system pressure generates sufficient force to lift the poppet and divert excess flow to the tank port. This design delivers fast, reliable response to pressure surges and maintains stable system pressure across varying flow conditions. The URPX-10A-20 is a compact, cartridge-style valve suited for manifold or block mounting, making it an ideal choice for hydraulic power units, test stands, and machine tool hydraulic systems requiring dependable pressure control.
