SUMMARY:  Cartridge

Due to extremely high demand, please call 888-651-5712 for availability

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.

  • This valve is direct actuated and requires no minimum hydraulic pressure for operation.
  • The solenoid tube assembly is fatigue rated for 3600 psi (250 bar) service.
  • Port 3 is the preferred inlet for this valve.
  • This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
  • 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.
