Hydraulic Valves

Direct Acting Relief Valves of RD Series

Direct acting relief valves of RD series are used to limit the pressure in a hydraulic system. No initial stage allows for a faster response to the increased pressure and results in better tolerance to oil contamination.

Maximum pressure 350 bar, maximum permissible flow from 95 to 760 lpm.
