The Sun Hydraulics DMDATPN912 (DMDATPN912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic system applications. This direct-acting, balanced spool directional valve excels in environments requiring reliable and consistent control. With its robust construction, the solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring durability under demanding conditions. The valve features closed transitions between its two positions (Spools B and R), which enhances performance limits while sacrificing some capacity. This design choice results in faster and more consistent response times when the valve is utilized as a pilot control, where capacity is less critical. The DMDATPN912 operates without needing a minimum hydraulic pressure, facilitating its use in a variety of systems. Additionally equipped with EPDM seals, this model is specifically suited for systems using phosphate ester fluids; however, these seals are vulnerable to damage if exposed to petroleum-based fluids. Its wet armature design means that the working fluid surrounds the armature which could lead to higher temperatures if the coil remains energized over long periods - an important consideration for system designers. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades, allowing coils to be mounted on the tube in either direction. The design also incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response times of 50 ms. It supports switching frequencies up to 15,000 cycles/hr and features manual overrides that require minimal force. This compact yet powerful valve is essential for precise fluid control in various hydraulic 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.
