The Sun Hydraulics DMDADAN71219 (DMDADAN71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in various hydraulic systems, featuring a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The valve's spools B and R remain closed during the transition between positions to enhance performance limits at the cost of lower capacity. However, this feature allows for faster and more consistent response times when used as pilot controls. The DMDADAN71219 requires no minimum hydraulic pressure to operate, which simplifies integration into hydraulic circuits. It includes options such as manual overrides with detent mechanisms (D or L control) designed for temporary actuation; these manual controls are rated for approximately 7,000 cycles. The valve is equipped with EPDM seals intended specifically for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. This model also benefits from a wet armature design where the working fluid surrounds the armature, which is crucial to consider if the coil remains energized over extended periods since heat can degrade certain types of fluids. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this component. Additionally, Sun's floating style construction minimizes internal parts binding due to installation torque or machining variations in cavity-cartridge setups. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). This robust design and versatile configuration make the DMDADAN71219 an excellent choice for advanced hydraulic systems requiring reliable directional control and rapid response times.

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.
- Spools B and R are closed in the transition between their 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.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
- 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.
- Coils are interchangeable with other Sun Series 1 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.
