The Sun Hydraulics DMDADPN (DMDADPN) is a high-performance solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional control. This model is specifically designed to be fatigue rated for demanding 5000 psi (350 bar) service environments, ensuring durability and reliability in high-pressure applications. The DMDADPN features closed transitions between Spools B and R, enhancing performance limits while reducing capacity, which is ideal in pilot control scenarios where rapid and consistent response times are critical rather than flow capacity. This valve operates effectively without the need for minimum hydraulic pressure, offering flexibility and ease of integration into various hydraulic systems. The DMDADPN model supports manual override through a detent mechanism intended for temporary actuation, with an estimated mechanical life of around 7,000 cycles. It is compatible with EPDM seals when used in systems with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. A notable feature of the DMDADPN valve is its wet armature design, where the working fluid surrounds the armature which can be a consideration during extended periods of coil energization due to potential fluid degradation at elevated temperatures. The valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for added installation versatility. Additionally, it incorporates Sun\u2019s floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 12 gpm (45 L/min), and swift typical response times of about 50 ms, the Sun Hydraulics DMDADPN offers robust performance for sophisticated hydraulic control applications.

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.
