The Sun Hydraulics DMDAXPN924N (DMDAXPN924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and high capacity for pressure endurance, being fatigue rated for 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times especially in pilot control applications where capacity is less critical. The DMDAXPN924N operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It incorporates a wet armature design; the working fluid surrounds the armature which helps in heat management but requires consideration of fluid type to avoid breakdowns or varnish formation that could impair functionality. Specifically, cartridges with EPDM seals are recommended for systems using phosphate ester fluids to prevent seal damage. Further enhancing its utility, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This model is equipped with manual override options including a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve has a flow capacity of 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Quick response times are typical at around 50 ms, with maximum leakage at high pressures kept minimal. This makes the DMDAXPN924N an efficient choice for dynamic systems requiring precise control and reliability.

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.
