The Sun Hydraulics DMDATRN628 (DMDATRN628) 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 engineered to operate without minimum hydraulic pressure, enhancing its reliability and ease of use across various applications. The valve features a robust design with spools B and R that are closed during the transition between positions, optimizing performance by ensuring faster and more consistent response times especially suitable for pilot controls. The DMDATRN628 incorporates a wet armature design where the working fluid surrounds the armature. This design aspect is crucial as it can affect the longevity and functionality of the valve if the coil remains energized for extended periods, potentially leading to breakdowns in certain fluid types at high temperatures. Additionally, this model uses EPDM seals specifically tailored for systems with phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based substances. Interchangeability is a key feature of this valve as its coils can be swapped with other Sun Series 1 solenoid products and mounted in either direction to suit different installation requirements. The floating style construction minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a capacity of 12 gpm (45 L/min) and a maximum operating pressure of 5000 psi (350 bar), the DMDATRN628 ensures efficient flow control within your hydraulic circuit. Its quick response time of approximately 50 ms coupled with a manual override feature makes it adaptable for various operational scenarios requiring precise manual interventions. The durability of this model is evident from its mechanical life expectancy of around 7,000 cycles for models equipped with manual control assemblies D, L, or T.

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.
