The 1VR200-P-35-S-XXX relief valve is produced by Vickers for the Relief Valves series. It protects hydraulic automation circuits by diverting fluid when pressure rises above a predefined limit. The valve is pilot operated, so a small pilot flow modulates the main poppet for stable control. A screw-in cartridge installation simplifies manifold assembly, and the body fits the A16102 cavity. Working limits span from 30 bar to 350 bar, accommodating low-pressure standby and high-pressure work modes. The factory setting opens at 190 bar, and a leak-proof screw lets technicians adjust this set point without external oil escape. Three valve ports are present, and the interface is cartridge only for direct block integration.
The design handles a continuous flow of 200 L/min, giving the circuit ample capacity to relieve pressure spikes without excessive rise. When closed, internal bypass is limited to 0.25 cc/min, which reduces energy loss and keeps fluid temperature stable during standby. Overall length is 4.800 in, and height is 37.998 mm, dimensions that help builders position the component inside compact manifolds. These size and performance characteristics provide dependable pressure regulation for medium-flow hydraulic equipment where space efficiency and low leakage are priorities.
