The Sun Hydraulics DMDADNN624 (DMDADNN624) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is particularly notable for its high performance and reliability in various applications. It operates with no minimum hydraulic pressure required, making it versatile for different operational settings. The valve is designed to be fatigue rated for 5000 psi (350 bar) service, ensuring durability even under high-pressure conditions. The DMDADNN624 incorporates closed transitions between spool positions B and R, which enhances performance by providing faster and more consistent response times. This feature makes the valve suitable for pilot control applications where rapid actuation is critical. Additionally, the valve's manual override mechanism includes a detent feature meant for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of the DMDADNN624 allows the working fluid to surround the armature, which can be beneficial but requires consideration regarding heat generation if the coil remains energized over extended periods. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades. This model also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), this valve is equipped to handle demanding tasks efficiently. Its quick response time (typical 50 ms) and robust construction make it an ideal choice for systems requiring reliable directional control in challenging industrial environments.

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.
