The 7VR250P16T202H110S-377 valve belongs to the Relief Valves series manufactured by Vickers and provides pressure control in hydraulic automation by venting flow when limits are reached. It functions as a ventable relief valve, and its screw-in cartridge format lets it seat directly in a manifold, while line mounting makes exterior plumbing possible. System pressure is adjusted through a leakproof screw that resists loosening, and the unit ships preset to 100 bar (1454 psi). During operation it can be tuned as low as 10 bar (145 psi) and safely withstands up to 210 bar (3053 psi). The flow path accommodates up to 200 L/min (53 gpm), enabling protection for medium-capacity cylinders, motors, and pumps.
Hydraulic hookup uses a 1 in SAE port so standard fittings connect without adapters. A steel housing provides structural strength and corrosion resistance while limiting the body to 3.5 in (88.9 mm) in length and 6.8 in (172.7 mm) in height for compact installation. Internal seat design restricts leakage to 35 cc/min, preserving circuit efficiency during standby. Continuous service is allowed from −40 °C (−40 °F) up to 120 °C (248 °F), so the valve operates reliably in cold outdoor equipment or high-temperature industrial presses. These dimensional, material, thermal, and leakage characteristics define the valve’s performance envelope for consistent over-pressure protection.
