E-RPEC PILOT-OPERATED RELIEF VALVES (MODERATELY FAST)
Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
