The Sun Hydraulics DMDATPN612N (DMDATPN612N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is characterized by its robust construction and optimized performance features. It operates without the need for a minimum hydraulic pressure, making it highly effective in various applications. The valve features a fatigue-rated solenoid tube assembly that can handle services up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. The transition between the spool positions B and R is closed, which enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design of the valve means that the working fluid surrounds the armature which may affect fluid integrity if subjected to prolonged heat exposure during coil energization. This model also incorporates interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. Additionally, it offers a manual override feature with a detent mechanism designed for temporary actuation only. With capabilities like a maximum flow capacity of 12 gpm (45 L/min), rapid response time typically around 50 ms, and maximum operating pressure up to 5000 psi (350 bar), this valve is an excellent choice for demanding hydraulic applications requiring precise directional control and 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.
