The Sun Hydraulics DMDATAN928 (DMDATAN928) 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 tailored for applications requiring robust performance 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 spool positions B and R, enhancing performance by ensuring faster and more consistent response times particularly in pilot control applications where capacity is less critical. The DMDATAN928 incorporates a fatigue-rated solenoid tube assembly suitable for demanding applications. It requires no minimum hydraulic pressure to operate, making it highly versatile across various hydraulic setups. The manual override mechanism included in models with D or L control is designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. Notably, the valve uses EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged coil energization but may affect fluid integrity over time. Additionally, this model benefits from Sun\u2019s floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and setup. With its robust build and precise control capabilities, the DMDATAN928 is an excellent choice for sophisticated hydraulic system applications requiring reliable directional control and swift response times.

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.
