Danfoss 158B4520 Hydraulic Check Valve 95LPM 350 Bar

The Danfoss 158B4520 hydraulic check valve enables one-way flow in hydraulic circuits while preventing backflow, a function essential for protecting pumps, actuators, and other system components. It carries a forward flow rating of 95 LPM and is rated for system pressures up to 350 bar, making it suitable for demanding industrial and mobile hydraulic installations. Identified by part number 158B4520 and manufactured by Danfoss, this valve is designed to integrate into circuits where direction of flow must be reliably controlled to maintain pressure integrity and prevent reverse flow after pumps or in branches of the hydraulic network. In use, the check valve opens to allow flow in the intended direction and automatically closes to stop reverse flow when the upstream pressure drops, helping to safeguard equipment and stabilize circuit operation.
