The Sun Hydraulics DMDAXBV914 (DMDAXBV914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is fatigue rated for demanding 5000 psi (350 bar) service environments, making it ideal for robust applications. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times particularly useful in pilot control systems where capacity is less critical. The DMDAXBV914 operates without requiring a minimum hydraulic pressure, which facilitates its use in a variety of systems with varying pressure levels. It includes options for manual override controls (D, L, T types), which are designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Special attention is needed regarding the valve\u2019s EPDM seals; these are suitable only for systems using phosphate ester fluids and must avoid contact with petroleum-based substances to prevent damage. Equipped with an interchangeable coil system compatible with other Sun Series 1 solenoid products, the valve offers flexible installation options and easy maintenance. Its wet armature design helps in cooling but requires consideration of fluid characteristics as prolonged exposure to heat might degrade certain fluid types. The valve's construction incorporates Sun's floating style design to minimize internal parts binding due to installation torque or machining variations. With a capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDAXBV914 is engineered to meet stringent performance criteria while maintaining reliability and durability in challenging industrial 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.
