The Hydraforce 5613481V (5613481V) is a screw-in, cartridge-style, pilot-operated relief valve with an integrated reverse free flow check valve. It is designed for use as a pressure-limiting device in demanding hydraulic circuits that require fast response, low hysteresis, minimal leakage, and low pressure override capabilities. The RV50-28X model blocks flow from port 1 to port 2 until the pressure at port 1 reaches a sufficient level. Once activated, the relief flow path allows fluid to move from port 1 to port 2. Additionally, it permits reverse flow from port 2 to port 1 when the pressure at port 2 exceeds that of port 1. This valve is rated for higher operating pressures up to 345 bar (5000 psi) and offers various adjustment options that cannot be backed out of the valve. It can operate in either relief valve mode or check valve mode and features a built-in reverse flow check valve for enhanced versatility. Constructed with a hardened spool and cage, the RV50-28X ensures long-lasting durability and reliable performance. Its fast response time and compatibility with industry-common cavities make it an ideal choice for applications requiring precise and efficient pressure control in hydraulic systems.
