The Sun Hydraulics DMDAXNN224 (DMDAXNN224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve is particularly noted for its robust construction with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The DMDAXNN224 features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. This model is engineered to operate without minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual override controls (D, L, T types), which have a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Another key feature of the DMDAXNN224 is its wet armature design that allows the working fluid to surround the armature, potentially affecting fluid integrity if the coil remains energized over extended periods. The valve supports a flow capacity of up to 12 gpm (45 L/min) and offers rapid response times typical at around 50 ms. It also boasts interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal part binding due to installation variances or cavity/cartridge machining errors. Overall, the DMDAXNN224 provides a reliable solution for directing flow in hydraulic systems requiring precise control and rapid actuation under varying pressure conditions while maintaining durability and performance integrity.

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.
