7VR250P16T351H12S-377

The 7VR250P16T351H12S-377 valve is part of the Relief Valves series manufactured by Vickers for hydraulic automation systems that require controlled over-pressure protection. A screw-in cartridge installation allows the unit to fit directly into a manifold, while a steel housing withstands mechanical stress common in high-pressure blocks. Pressure setting is adjusted through a leakproof screw so tampering or vibrational loosening is minimized during service. The factory set pressure of 210 bar means the valve ships pre-calibrated for typical circuit requirements, and operation can start as low as 30 bar so the device begins regulating well before components reach damaging limits.

Line mounting places the valve directly in the pressure path where it relieves at up to 350 bar, defining the maximum working ceiling for the protected circuit. The design accepts a rated flow of 200 L/min, enabling use on pumps and actuators with high delivery rates. Internal leakage is limited to 35 cc/min, keeping energy losses and tank return flow low when the element is closed. Together these characteristics support reliable pressure limitation without excessive bypass flow, making the 7VR250P16T351H12S-377 suitable for demanding industrial hydraulic loops.
