The Sun Hydraulics DMDADAN299 (DMDADAN299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. Its spools are closed during the transition between positions to enhance performance by providing faster and more consistent response times, particularly when used as pilot controls. The DMDADAN299 requires no minimum hydraulic pressure to operate, which simplifies integration into various hydraulic systems. It includes manual override options with a detent mechanism intended for temporary actuation, supporting up to approximately 7,000 cycles. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature\u2014important to consider if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures. The interchangeable coils with other Sun Series 1 solenoid products add versatility in maintenance and replacement processes. Key specifications include a flow capacity of up to 12 gpm (45 L/min), quick response times typically around 50 ms, and maximum operational pressures up to 5000 psi (350 bar). The robust construction minimizes internal part binding thanks to Sun's floating style construction, ensuring reliability even under varying installation conditions or cavity/cartridge machining discrepancies. This makes the DMDADAN299 an essential component for systems requiring reliable and precise fluid control in demanding environments.

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.
