The Sun Hydraulics DNDATSV912 (Material Number: DNDATSV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It is engineered to perform efficiently without the need for minimum hydraulic pressure and features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar). The valve offers multiple manual override options, though these are not compatible with weatherized coils. Models with the D or L control include a detent mechanism intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The valve is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. This cartridge employs a wet armature design that allows the working fluid to surround the armature, which can influence performance if the coil remains energized for extended periods due to potential fluid breakdown at higher temperatures. The solenoid's magnetic design provides high efficiency, ensuring reliable valve shifting with significant spool actuating force per watt consumed. Coil options are extensive, including various termination and voltage configurations with optional surge protection. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction. For enhanced environmental protection, additional weatherized coils and kits are available. Designed using Sun's floating style construction to reduce internal part binding risks from excessive installation torque or machining variations, this cartridge fits T31A cavities and offers a capacity of 10 gpm (40 L/min). It operates at pressures up to 5000 psi (350 bar) with typical response times around 50 ms and maximum leakage rates of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With a switching frequency of up to 15,000 cycles per hour and requiring minimal manual override force and stroke dimensions, this robust component is well-suited for demanding hydraulic applications.
