Two-position, 3-way directional cartridges are 6-port (port 5 is not used) directional valves that can be configured with up to 5 different spool configurations. The supply port is port 3 and all ports will accept 5000 psi (350 bar). Capacity for these pilot-to-shift valves is dependent on the spool type specified.

  • Leakage listed in technical data is for each path.
  • Pressure at port 6 directly opposes port 1.
  • Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
  • 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.
