Technical specifications

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.

  • The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
  • This valve is direct actuated and requires no minimum hydraulic pressure for operation.
  • All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection.
  • Coil connector options offer ratings up to IP69K. See individual coil product pages for details.
  • This cartridge utilizes both 740 Series high-power and 747 Series hazardous location coils.
  • This cartridge has an option for manual override. See the CONFIGURATION section.
  • On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles.
  • 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.
  • The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
  • Coils can be mounted on the tube in either direction.
  • 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.
  • The R-spool is closed in the transition between its two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.

  • What parts of the Sun cartridge valve are field serviceable?
  • How big is a drop of hydraulic oil?  
  • Direct acting or pilot operated - what do I use?
  • Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require different clearances.
  • An additional 2.00 inches (50,8 mm) beyond the valve extension is needed for coil installation and removal.
