The Hydraforce RVCV56-20A-0-P-61/50 (5612540P.50) is a screw-in, cartridge-style, direct acting poppet relief valve equipped with a reverse flow check valve. This product is designed to function as a pressure limiter and regulator in demanding hydraulic circuits that require features such as fast response, low hysteresis, minimal leakage, low pressure override, and reverse free flow. The valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to displace the poppet from its seat, allowing relief flow to discharge to port 2. Additionally, it facilitates reverse flow from port 2 to port 1 when the differential pressure exceeds the check spring value. The RVCV56-20X has a maximum pressure capacity of 420.6 bar (6100 psi) at port 1 and features adjustments that cannot be backed out of the valve for safety and reliability. Its hardened spool and cage ensure long life and fast response to pressure surges. The adjustable pressure range spans from 137.9 to 420.6 bar (2000 to 6100 psi), with crack pressures defined at specific flow rates. This valve supports a maximum flow rate of up to 113.6 lpm (30 gpm) from port 1 to port 2 and up to 174.1 lpm (46 gpm) in reverse direction from port 2 to port 1. It maintains minimal internal leakage rates of up to 0.53 ml/min under specified conditions. Suitable for various operating temperatures depending on seal material used, it can accommodate fluid temperatures ranging from -40 \u00b0C with buna N seals up to +204 \u00b0C with viton seals. The installation specifications recommend using VC16-2 variation 'a' cavities for higher flows with an installation torque between 199 and 207.4 N-m (147 to 153 ft-lb). Seal kits are available for maintenance purposes under part number SK16-2X-B depending on seal options chosen.
