The Sun Hydraulics DMDAXAV912 (DMDAXAV912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and reliable operation in diverse hydraulic systems. Notably, it features a fatigue rating suitable for 5000 psi (350 bar) service, making it ideal for high-pressure applications. The valve operates efficiently with no minimum hydraulic pressure required, facilitating its use in various fluid power circuits. The DMDAXAV912 incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times during operation. This characteristic is particularly beneficial in applications where pilot controls are utilized, as the capacity becomes a secondary concern to response time. Additionally, the model is equipped with interchangeable coils from Sun Series 1 solenoid products, which can be mounted in either direction on the tube. It also utilizes a wet armature design; this design involves the working fluid surrounding the armature which may be subject to heat during prolonged energization. The construction of the valve includes Sun's floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. The manual override feature present in models with D or L control uses a detent mechanism intended for temporary actuation only. With a mechanical life expectancy of approximately 7,000 cycles and various manual control configurations available, this valve adapts well to different operational needs while maintaining durability and reliability.
