The Sun Hydraulics DMDAXAV297 (DMDAXAV297) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility in various applications. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar), making it suitable for high-pressure environments. The valve's design includes closed transitions between spool positions B and R, which not only ensures faster and more consistent response times when used as pilot controls but also elevates performance limits at the cost of lower capacity. This model incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting performance if exposed to heat for prolonged periods. Notably, this model supports interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding due to installation torque or cavity-cartridge machining variations. Additional specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and a manual override mechanism designed primarily for temporary actuation with an expected mechanical life of about 7,000 cycles. The DMDAXAV297 also offers easy maintenance and compatibility with standardized cavity T11A from Series 1. This robust configuration makes it an ideal choice for applications requiring reliable directional control in sophisticated hydraulic systems.

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.
