The Sun Hydraulics DMDAXNN224N (DMDAXNN224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and ability to operate without minimum hydraulic pressure, making it highly versatile across various applications. It features a fatigue-rated solenoid tube assembly capable of withstanding pressures up to 5000 psi (350 bar), ensuring durability and reliability even under demanding conditions. The valve's spools, designated B and R, are closed during the transition between positions, which enhances performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDAXNN224N includes options for manual override controls (D, L, T types), each designed with a detent mechanism for temporary actuation and an expected mechanical life of approximately 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature to manage heat dissipation effectively; however, this may affect fluid integrity over extended periods of energization. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal part binding due to installation variances. With a switching frequency capability of up to 15,000 cycles per hour and quick response times typically around 50 ms, the DMDAXNN224N is optimized for high-cycle applications requiring precise control and rapid actuation.

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.
