The Sun Hydraulics DMDATRN228 (DMDATRN228) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating for 5000 psi (350 bar) service. The valve is particularly noted for its closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times during operation. This makes it an ideal choice for applications requiring precise control with minimal hydraulic pressure. The DMDATRN228 also incorporates a wet armature design wherein the working fluid surrounds the armature, which is beneficial in reducing wear but requires consideration of fluid type due to potential heat generation when the coil is energized for extended periods. It's compatible with EPDM seals specifically designed for use with phosphate ester fluids, though these seals must not be exposed to petroleum-based fluids as they can cause damage. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easier maintenance and replacement processes. Additionally, the floating style construction of the valve minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. With a maximum operating capacity of 12 gpm (45 L/min) and swift typical response times of 50 ms, this valve ensures efficient flow control in various hydraulic systems. The manual override feature requires a force of 5 lbs at 1000 psi on Port 1 and allows for an override stroke of .10 inches (2.5 mm), providing temporary manual actuation when needed. The DMDATRN228\u2019s compact and durable design, coupled with its technical capabilities, makes it suitable for demanding applications where reliability and precision are critical.

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.
