The Sun Hydraulics DMDATRN812N (DMDATRN812N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust service with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications requiring precise control such as in pilot operations. This model is characterized by its wet armature design which allows the working fluid to surround the armature, helping in heat dissipation when the coil is energized for extended periods. However, users should be cautious with fluid selection as some fluids can degrade under heat, affecting performance. The valve\u2019s solenoid coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction for flexible installation. The DMDATRN812N incorporates Sun's floating style construction which minimizes internal parts binding that could occur due to excessive installation torque or cavity/cartridge machining variations. It also offers manual override options with a detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. This model also supports a switching frequency up to 15,000 cycles/hr and has typical response times of about 50 ms. The manual override requires minimal force (5 lbs at 1000 psi), making it user-friendly during manual operation scenarios.

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.
