Pilot Operated Relief Valve (Cartridge)
Pilot operated (indirect acting) cartridge relief valve rated to 200 l/min — by far the highest flow capacity in the Renman relief valve range. The pilot operating principle delivers a much flatter pressure-versus-flow characteristic than a direct acting valve, keeping cracking pressure overshoot low and maintaining consistent set-pressure accuracy even at high flow rates.
It installs into a standard M33x2 cavity in a manifold block, and is the natural choice for main-line system relief in high-capacity power units and mobile plant hydraulic circuits.
