The Sun Hydraulics DMDADNN299 (DMDADNN299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features spools B and R which are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times particularly in applications where capacity is less critical. This model is also equipped with a manual override feature that includes a detent mechanism designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. It uses EPDM seals suitable for systems utilizing phosphate ester fluids, while petroleum-based fluids should be avoided as they can damage the seals. Additionally, the valve incorporates a wet armature design where the working fluid surrounds the armature; this design consideration is crucial for applications where the coil may be energized for extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easier maintenance and replacement processes. The construction employs Sun's floating style to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a typical response time of 50 ms and maximum valve leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Each unit weighs approximately 0.60 lb (0.30 kg), ensuring it is robust yet manageable for various installation 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.
