The Sun Hydraulics DMDATAN728 (DMDATAN728) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure and features a fatigue rating suitable for up to 5000 psi (350 bar) service. The specialized design includes closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. Equipped with EPDM seals, the DMDATAN728 is optimized for use with phosphate ester fluids, although it should not be exposed to petroleum-based substances which could degrade the seals. Its wet armature design allows the working fluid to surround the armature, which can be a consideration when the coil is energized over extended periods as heat generation might impact certain types of fluids. The model also integrates Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. This valve supports a maximum flow capacity of 12 gpm (45 L/min) and incorporates interchangeable coils from other Sun Series 1 solenoid products that can be mounted in either direction on the tube. It features a manual override mechanism with a mechanical life expectancy of about 7,000 cycles and requires minimal force for operation. The DMDATAN728 also boasts rapid response times typically around 50 ms and maintains low leakage rates even under high pressures. Its robust construction and versatile design make it an ideal choice for demanding hydraulic applications requiring reliable directional control and swift actuation.

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.
