The RV1-10-S-8T-18/ unit belongs to the Relief Valves series from Vickers. Designed to cap system pressure in hydraulic automation loops, it uses direct acting operation so the poppet lifts immediately when the threshold is reached. Pressure adjustment is performed by a screw, permitting maintenance personnel to fine-tune the setting in situ. The cartridge installs in a C-10-2 cavity, letting designers drop it into standard aluminum or steel manifolds. Two valve ports channel oil from the service line to tank, and external piping attaches through a 1/2 in SAE port for common hose hardware. A factory set pressure of 62 bar ships with the product, while a minimum working value of 247 psi ensures low-pressure standby circuits remain protected. The poppet style sealing arrangement minimizes leakage past the seat and maintains stable relief characteristics under fluctuating load conditions.
The RV1-10-S-8T-18/ handles a rated flow of 30 L/min, supplying sufficient bypass capacity for medium-sized actuators without excess pressure rise. Acceptable fluid cleanliness is limited to ISO code 18/16/13, which helps prevent erosion of the seating surfaces. Buna-N seals are fitted to withstand standard mineral-oil hydraulics and remain resilient after repeated pressure cycles. The valve continues to function at ambient temperatures down to –40 °C, supporting cold-start operation in outdoor equipment. Physical dimensions of 63.50 mm in length, 50.80 mm in width, and 147.32 mm in height give a compact footprint that fits densely populated control blocks. Together these characteristics allow the cartridge to protect pumps and cylinders while occupying minimal space and demanding only routine filtration.
