The Sun Hydraulics DMDATRN812 (DMDATRN812) is a solenoid-operated, 3-way, 2-position cartridge valve featuring direct-acting, balanced spool directional control. This valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It operates without the need for minimum hydraulic pressure, enhancing its versatility in various applications. A notable feature of the DMDATRN812 is its closed transition between positions B and R, which allows for faster and more consistent response times, particularly beneficial when used as pilot controls. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability under demanding conditions. Additionally, the valve incorporates a wet armature design where the working fluid surrounds the armature; this design choice is crucial for understanding environmental compatibility, especially regarding fluid types that could degrade at high temperatures. The manual override feature equipped with detent mechanisms (D or L control) supports temporary actuation with an expected mechanical life of approximately 7,000 cycles. For maintenance and customization, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This interchangeability extends to its installation flexibility due to Sun's floating style construction that minimizes internal binding caused by excessive installation torque or machining variations in cavity-cartridge systems. This valve is particularly suited for systems requiring precise control over fluid direction and pressure within hydraulic circuits while maintaining robust performance and reliability in industrial environments.

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.
