The Sun Hydraulics DMDAXRN (DMDAXRN) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. Featuring a direct-acting, balanced spool design, this valve ensures reliable operation with no minimum hydraulic pressure requirement. It is particularly suited for use as pilot controls where its closed transition between spool positions enhances response times and consistency without compromising on performance limits. This model boasts a robust fatigue rating of 5000 psi (350 bar), making it ideal for demanding environments. The DMDAXRN incorporates a wet armature design, which helps in cooling but requires consideration of fluid type as heat can affect fluid integrity over prolonged periods. It is compatible with EPDM seals specifically for systems using phosphate ester fluids, while its exposure to petroleum-based fluids should be avoided to prevent seal damage. Engineered for versatility, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different system requirements. The manual override feature included in models with D or L control is designed for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. Additional features include a maximum flow capacity of 12 gpm (45 L/min), quick response time typically around 50 ms, and a switching frequency capable of reaching up to 15,000 cycles per hour. For installation ease and reliability, the valve uses Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or machining variations. The compact design weighs only 0.60 lb (0.30 kg) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm), ensuring easy handling and integration into various hydraulic systems.

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.
