The Sun Hydraulics DMDAXNV297 (DMDAXNV297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool valve is suitable for use in applications requiring reliable switching and directional control of hydraulic fluids. The valve operates efficiently with a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min), making it versatile for various hydraulic tasks. Featuring a robust design, the DMDAXNV297 incorporates a wet armature setup where the working fluid surrounds the armature, enhancing heat management during prolonged coil energization. This design consideration is crucial for maintaining fluid integrity, especially when using water-glycol mixtures which are prone to breakdown and varnish formation under high temperatures. The valve\u2019s response time is exceptionally quick at approximately 50 ms, ensuring rapid actuation and system responsiveness. The DMDAXNV297 also boasts interchangeable coils with other Sun Series 1 solenoid products, offering flexibility in maintenance and replacement procedures. It includes a manual override with a detent mechanism designed primarily for temporary actuation, supporting about 7,000 cycles mechanically. Additionally, the construction features Sun\u2019s floating style to minimize internal part binding due to installation torque or machining variations of cavity/cartridge. This valve uses EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. Its switching frequency can reach up to 15,000 cycles per hour, highlighting its capability for high-duty applications. Overall, the Sun Hydraulics DMDAXNV297 provides a reliable solution for directing flow efficiently in advanced hydraulic systems where performance and durability are critical.

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.
