The Sun Hydraulics DMDAMBV71299 (DMDAMBV71299) is a solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This model is particularly noted for its capability to operate without minimum hydraulic pressure, featuring a spool that remains closed during transitions between positions to enhance performance limits at the cost of lower capacity. This feature makes it ideal for use as pilot controls where capacity is less critical but fast and consistent response times are necessary. The valve boasts a robust design with a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly, ensuring durability under high-pressure conditions. It is equipped with manual override options including detent mechanisms on models with D or L control, suitable for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The DMDAMBV71299 uses EPDM seals designed specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. The valve employs a wet armature design where the working fluid surrounds the armature\u2014important to consider as prolonged energization can lead to fluid degradation in certain conditions. Its construction incorporates Sun\u2019s floating style to minimize internal parts binding caused by excessive installation torque or machining variations of cavity/cartridge. With a capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, along with maximum operating pressures up to 5000 psi (350 bar), this valve ensures efficient and reliable operation in various hydraulic applications.
