Normally open, direct-acting, 2-way directional cartridges are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.

  • Port 3 can be used as a work port.
  • The flow path between port 2 and port 3 is bidirectional.
  • Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
  • Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
  • Pressure at port 4 is directly additive to the setting of the valve.
  • This valve is not bistable; it is capable of modulating between the two positions shown.
  • Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
  • 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.
