The Sun Hydraulics DMDAXRN914 (DMDAXRN914) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), this valve is well-suited for demanding applications requiring reliable directional control. The DMDAXRN914 features a direct-acting, balanced spool with closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times particularly useful in pilot control setups where capacity is less critical. This model incorporates a wet armature design, meaning the armature is immersed in the hydraulic fluid, which can affect fluid properties if the coil remains energized over extended periods. It\u2019s important to consider the type of hydraulic fluid used, as EPDM seals in this cartridge are specifically intended for phosphate ester fluids and can be damaged by exposure to petroleum-based products. The DMDAXRN914 also benefits from Sun's floating style construction which minimizes internal part binding due to installation variances or machining discrepancies. Manual override options with detent mechanisms are available for temporary actuation, supporting up to approximately 7,000 cycles mechanically. Additionally, this model\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube assembly. Each valve is designed to switch at frequencies up to 15,000 cycles per hour and has a typical response time of about 50 ms. The compact design includes a manual override force requirement of 5 lbs at 1000 psi (Port 1) and an override stroke of .10 inches (2.5 mm), making it versatile for various installation environments without compromising on functionality or reliability.

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.
