Product Overview
The Rexroth DA6VP2A50/350FSM (Material Number: R901224247) is a pilot-operated pressure unloading valve engineered for precise hydraulic system pressure management. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this valve is designed to automatically unload system pressure when a predetermined pilot pressure is reached, thereby reducing energy consumption and minimizing heat generation in high-pressure hydraulic circuits. The DA6VP2A50/350FSM operates on a balanced spool principle with a pilot stage, ensuring fast response and stable pressure regulation. Its robust construction and precision-machined internal components make it ideal for demanding industrial applications where reliable pressure control and energy efficiency are critical.
