E-RDDA DIRECT-ACTING RELIEF VALVE
SYMBOL
DESCRIPTION
Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant, immune to silting and are very fast.
Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
