The Sun Hydraulics DMDAXBNHN24AB (DMDAXBNHN24AB) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust industrial applications requiring precise control over fluid handling. The valve features a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), making it suitable for a wide range of hydraulic systems. Key to its design is the fatigue-rated solenoid tube assembly which ensures reliable operation under continuous high-pressure conditions. The valve\u2019s spools, B and R, maintain a closed position during transitions, enhancing performance by ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model also incorporates manual override capabilities with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles. The DMDAXBNHN24AB employs EPDM seals when configured for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to cool the armature but requires consideration of fluid type as some may degrade under prolonged heat exposure. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this unit, allowing for easier maintenance and part replacement. Furthermore, the valve benefits from Sun's floating style construction which minimizes internal binding caused by installation torque or machining variations in cavity/cartridge setups. Overall, the DMDAXBNHN24AB offers a reliable solution for demanding hydraulic control applications where durability and precision are paramount.

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.
