The Sun Hydraulics DMDAXNV924 (DMDAXNV924) is a solenoid-operated 3-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. This model is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar), with a flow capacity of up to 12 gpm (45 L/min). The valve features a rapid response time of approximately 50 ms and is capable of handling switching frequencies up to 15,000 cycles per hour. The design includes interchangeable coils compatible with other Sun Series 1 solenoid products, allowing for flexible application and installation. The DMDAXNV924 incorporates advanced features such as closed transitions between spool positions B and R, enhancing performance limits by ensuring faster and more consistent response times during pilot control operations. It operates without requiring a minimum hydraulic pressure, adding to its versatility in various hydraulic systems. Additionally, the manual override function is equipped with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. For environments using phosphate ester fluids, this model should be configured with EPDM seals to prevent damage from petroleum-based substances. The wet armature design of the valve ensures that the working fluid surrounds the armature which could be significant when dealing with prolonged coil energization and specific fluid types that may degrade under high temperatures. This valve also benefits from Sun\u2019s floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This feature aids in maintaining reliable operation and longevity of the component 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.
