The Sun Hydraulics DMDADPV828 (DMDADPV828) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is particularly noted for its robust construction and the ability to operate without minimum hydraulic pressure. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's design includes closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for pilot control applications where capacity is less critical. The manual override options available with this model (D, L, and T controls) are equipped with a detent mechanism intended for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of the valve helps in cooling but requires consideration of fluid characteristics as prolonged exposure to heat can degrade certain types of hydraulic fluids. Integration flexibility is further supported by interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. 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 maximum operating pressure of 5000 psi (350 bar). This model also features a compact design with a weight of just 0.60 lb (0.30 kg), making it suitable for various installation environments without compromising performance.

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.
