Ventable, pilot-operated, balanced-poppet 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. 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. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.

  • Because the modulating occurs inside the cartridge, these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
  • Suitable for use in load holding applications, providing that any valving on the vent port (port 3) is zero leak.
  • Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
  • A remote pilot relief on port 3 (vent) will control the valve below its own setting.
  • Valve is relatively insensitive to varying oil temperatures and oil borne contamination.
  • Main stage orifice is protected by a 150 micron stainless steel screen.
  • Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
