The Sun Hydraulics DMDAXPV624N (DMDAXPV624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. This direct-acting, balanced spool directional valve is tailored for systems requiring reliable operation under high pressure, with a fatigue rating suitable for 5000 psi (350 bar) service. The valve features a closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times during operation shifts, ideal for pilot control applications where capacity is less critical. The DMDAXPV624N operates without the need for minimum hydraulic pressure, providing flexibility in various hydraulic setups. It incorporates manual override options with detent mechanisms specifically designed for temporary actuation, supporting up to approximately 7,000 cycles. The wet armature design of this model means that the working fluid surrounds the armature which is beneficial for heat absorption but requires careful consideration of fluid type to avoid breakdowns; EPDM seals included in this model are compatible with phosphate ester fluids but not with petroleum-based substances. Furthermore, the interchangeable coils of this valve are compatible with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. The design also includes Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue arising from excessive installation torque or cavity/cartridge machining variations. With a switching frequency capability of up to 15,000 cycles per hour and rapid typical response times of 50 ms, the DMDAXPV624N ensures efficient and reliable performance in demanding applications.

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.
