The Sun Hydraulics DMDADAV914 (DMDADAV914) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed with a fatigue rating for 5000 psi (350 bar) service, making it suitable for rigorous applications. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times especially in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, adding to its versatility and ease of use in various hydraulic systems. It incorporates a wet armature design where the working fluid surrounds the armature which could be a consideration when using fluids that degrade at higher temperatures such as water-glycol mixtures. For manual operation, the DMDADAV914 includes a detent mechanism in the manual override designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. The valve also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction which provides flexibility during installation. The construction of this valve utilizes Sun's floating style to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This feature ensures reliable and consistent operation under varying mechanical conditions. Additionally, it has specific configurations for EPDM seals suitable for phosphate ester fluids while avoiding exposure to petroleum-based fluids to prevent seal damage. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being minimal at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). This model is essential for applications requiring robust control with high reliability and precision.

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.
