The Sun Hydraulics DMDAXNV824 (DMDAXNV824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. It features fatigue-rated solenoid tube assembly for service at pressures up to 5000 psi (350 bar), ensuring reliability and durability under demanding conditions. The valve's design includes closed transitions between Spools B and R, optimizing performance by allowing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model incorporates a wet armature design where the working fluid surrounds the armature, which is crucial for applications involving prolonged coil energization that may lead to heat build-up. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and has a swift typical response time of 50 ms. It also allows for manual override with a detent mechanism designed for temporary actuation, having a mechanical life expectancy of about 7,000 cycles. The DMDAXNV824 is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Additionally, it features interchangeable coils with other Sun Series 1 solenoid products and can accommodate various mounting orientations on the tube. The construction utilizes Sun's floating style to minimize internal part binding due to installation torque or machining variations in the cavity/cartridge setup. This model is designed to fit within a T11A cavity and supports switching frequencies up to 15,000 cycles per hour, making it an excellent choice for systems requiring high cycling frequency and precision fluid control.

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.
