Collection: SUN Pressure Reducing Cartridges

Reducing cartridges are normally open pressure control elements designed to reduce a high primary pressure at port 2 (inlet) to a controlled lower pressure (reduced pressure) at port 1 (outlet). The reduced pressure is determined by the spring adjustment plus any pressure at port 3 (adjustment spring chamber drain).

Sun Hydraulics reducing cartridges are available in variety of configurations with flow rates up to 80 gpm (320 L/min.).

  • Functionally interchangeable with reducing/relieving cartridges (same flow path, same cavity for a given frame size)
  • Fully adjustable up to and including 4500 psi (315 bar) with inlet pressures up to 5000 psi (350 bar), except air-piloted versions
