The Sun Hydraulics DMDADPN712 (DMDADPN712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. This direct-acting, balanced spool directional valve is engineered to operate effectively without minimum hydraulic pressure, making it versatile for various system configurations. The valve features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability in high-pressure environments. Designed with precision, the DMDADPN712 incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The manual override options available on models with D or L control are equipped with a detent mechanism intended for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design helps in cooling but requires consideration regarding the type of fluid used; it is compatible with EPDM seals specifically for phosphate ester fluids while avoiding petroleum-based substances to prevent seal damage. Additionally, its interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure capability of 5000 psi (350 bar). It also features a switching frequency up to 15,000 cycles per hour and manual override requirements that ensure ease of operation under varying pressures. The robust construction minimizes internal parts binding through its floating style construction, accommodating variations in installation torque and machining discrepancies. This makes the DMDADPN712 an ideal solution for systems requiring precise control and high reliability.

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.
