The DAAA model is no longer being produced by Sun Hydraulics.

The new DTAF is a direct replacement for the DAAA using the same cavity. It provides the same functionality in a new high-reliability design with zinc-nickel coating as standard.

Please contact our sales team for DTAF version.

Product Description

DAAA-MCN Technical Features

This solenoid-operated 2-way, 2-position cartridge is a direct-acting, balanced spool pilot valve used to pilot other full-flow valves. The valve is available in either a normally open or normally closed configuration.

This cartridge can be installed directly into a cavity in the end of many of Sun’s pilot operated and ventable valves to provide integrated pilot control.

  • 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.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • A manual push-type override is a standard feature.
  • Cartridge can be installed directly into a cavity in some Sun pilot operated and ventable cartridges to provide electrically operated pilot control functions. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function.
  • Highly efficient tube design requires only 12 Watts to shift the valve.
  • Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @ 350 bar).
  • 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.
  • A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
  • Coils are interchangeable with other Sun Series P pilot solenoid products and 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.
