The Sun Hydraulics DMDATRN (DMDATRN) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is characterized by its fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring reliability and durability in demanding applications. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDATRN operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes options for manual override controls (D or L control), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. This model also incorporates a wet armature design allowing the working fluid to surround the armature which helps in heat dissipation but requires consideration of fluid type due to potential breakdown at high temperatures. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Additionally, the valve employs Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With specifications like a maximum flow capacity of 12 gpm (45 L/min), rapid response time typically around 50 ms, and robust switching frequency up to 15,000 cycles/hr., the DMDATRN is equipped to handle rigorous industrial applications efficiently while maintaining precise control over hydraulic flow directions.

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.
