The RVD50-20P is a screw in, cartridge style, direct acting, poppet type, hydraulic safety relief valve intended for use as a pressure limiting device for common hydraulic circuit protection. The RVD50-20P is suitable for use as a safety accessory in category IV group 2 applications according to the pressure equipment directive (PED) 2014/68/EU.
The RVD50-20P blocks flow from port 1 to 2 until sufficient pressure is present at port 1 to force the poppet from its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low hysteresis, low pressure rise and low internal leakage.
