Product Overview
The HAWE RV1-8-S-0-30 is a direct-acting, spring-loaded pressure relief valve from HAWE Hydraulik’s proven RV series, engineered to protect hydraulic circuits from excessive pressure and to serve as a reliable back-pressure or safety control element. When system pressure exceeds the preset spring force, the valve poppet lifts off its seat and diverts flow to tank, thereby limiting pressure to the adjusted value. Its compact, leak-tight seat design makes it ideal for pilot circuits, clamping systems, and low-flow industrial applications where precise pressure limitation and dependable reseating are essential.
