Hydraulic Pilot-Operated Check Valve for Double-Acting Cylinders, BSP, FPDL

The FPDL type controlled check valve is a reliable safety component designed for hydraulic systems, effectively preventing unintended movements of double-acting actuators during both piston rod extension and retraction. It ensures secure operation with permissible flow directions V1 → C1 (simultaneously C2 → V2) and V2 → C2 (simultaneously C1 → V1), providing precise control and dependable performance. The valve body is manufactured from high-quality galvanized steel in sizes 1/4" and 3/8", or lightweight aluminum in 1/2" and 3/4", while the stem is made of hardened steel for maximum durability. Equipped with NBR seals, it guarantees excellent resistance to wear and hydraulic fluids, maintaining tightness even under demanding conditions. With an opening pressure of 3 bar and an operating temperature range from -20°C to +100°C, the valve is suitable for a wide variety of industrial applications. Two mounting holes, clearly visible in the design, allow for quick and secure installation, making the FPDL valve a practical and efficient solution for enhancing the safety and reliability of hydraulic systems.
