The Sun Hydraulics DMDADAV914N (DMDADAV914N) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is particularly noted for its high-performance capabilities due to the closed transitions between Spools B and R, enhancing response times and consistency when used as pilot controls. It operates without requiring a minimum hydraulic pressure, making it versatile for various applications. Designed with a fatigue rating of 5000 psi (350 bar), the DMDADAV914N ensures durability under high-pressure conditions. The valve incorporates EPDM seals suitable for systems using phosphate ester fluids, while caution is advised against exposure to petroleum-based substances which may damage the seals. Additionally, this model employs a wet armature design where the working fluid surrounds the armature; this could affect fluid properties if the coil remains energized over extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in installation and maintenance, allowing coils to be mounted in either direction on the tube. The construction of this valve uses Sun's floating style to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), response time typically around 50 ms, and maximum operating pressure up to 5000 psi (350 bar). The manual override feature requires minimal force and has an expected mechanical life of approximately 7,000 cycles. This robust valve is ideal for systems requiring reliable directional control with fast and consistent actuation.
