Description

The DPRH-20S is a direct-acting pressure relief valve designed to protect hydraulic systems from excessive pressure by automatically diverting excess hydraulic fluid to the tank once the preset pressure is reached. It features a guided poppet design with a cushioning arrangement for stable, low-noise operation and fast pressure response. The valve is built for reliable performance in demanding industrial and mobile hydraulic applications, including hydraulic power packs, machine tools, construction equipment, marine systems, and industrial automation.
