The Hydraforce RV50-28A-0-N-50 (5613480) is a screw-in, cartridge-style, pilot-operated relief valve with an integrated reverse free flow check valve. Designed for high-demand hydraulic circuits, this component serves as a pressure-limiting device that ensures fast response times, low hysteresis, minimal leakage, and low-pressure override capabilities. The valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 reaches a certain threshold. It allows relief flow from port 1 to port 2 and supports reverse flow when the pressure at port 2 exceeds that at port 1. This model is rated for operating pressures up to 345 bar (5000 psi) and features various adjustment options that are secured against accidental changes. It can function in either relief or check valve mode and includes a built-in reverse flow check valve. The hardened spool and cage enhance durability, while its industry-common cavity design facilitates compatibility with standard systems. The RV50-28A-0-N-50 can handle a maximum proof pressure of 620.5 bar (9000 psi) and burst pressure of up to 1275.5 bar (18500 psi). Its adjustable pressure range spans from 13.8 to 344.7 bar (200 to 5000 psi), with an approximate increment of 98.6 bar per adjuster turn. The valve supports a flow rate of up to 113.6 lpm (30 gpm) from port 1 to port 2 and maintains maximum internal leakage below 0.53 ml/min at up to 80% of the nominal setting. Temperature ratings vary depending on seal type: -40\u00b0C to +100\u00b0C with buna N seals; -26\u00b0C to +204\u00b0C with fluorocarbon seals; -54\u00b0C to +107\u00b0C with polyurethane or urethane seals; storage temperatures range between -40\u00b0C and +70\u00b0C. The unit weighs between approximately 0.240 kg and 0.31 kg depending on configuration, requiring installation torques ranging from 47.6 N-m to a maximum allowable torque of 67.8 N-m for secure mounting in VC10-2 cavities.
