The Hydraforce 5612903.M37 (5612903.M37) is a screw-in, cartridge-style, direct-acting poppet-type relief valve designed for pressure limiting in hydraulic circuits. This valve, known as the RVD58-20, effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet. It is engineered to provide rapid response to load changes, making it suitable for applications requiring minimal hysteresis, low pressure rise, and reduced internal leakage. The RVD58-20 is compact and economical while offering dynamic response capabilities to handle pressure surges efficiently. Its construction includes a hardened poppet and cage that ensure long-lasting performance. Users can select from optional spring ranges up to 350 bar (5076 psi) based on specific application needs. The valve features high durometer Buna and Fluorocarbon seals for reliable operation under varying conditions. Additionally, an optional cap is available for enhanced protection. An embossed QR code on the unit provides a serial number for easy identification and tracking of the component.
