  • Pilot-operated, relief cartridges are normally closed pressure regulating valves. When the pressure at the port 1 (inlet) reaches the valve setting, the valve starts to open to port 2 (tank), They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. A remote pilot relief on port 3 (vent) will control the valve below its own setting.
