The Sun Hydraulics DMDADPN71299 (DMDADPN71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its robust construction includes a fatigue-rated solenoid tube assembly suitable for demanding applications. Notably, the valve features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly when utilized as pilot controls. The DMDADPN71299 is equipped with interchangeable coils that can be mounted in either direction, compatible with other Sun Series 1 solenoid products. It incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue arising from excessive installation torque or cavity/cartridge machining variations. The manual override feature in this model is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This valve also employs a wet armature design where the working fluid surrounds the armature; this setup requires careful consideration of the fluid type used as it impacts the heat management within the system. Specifically configured cartridges with EPDM seals are intended for systems using phosphate ester fluids; however, they are vulnerable to damage if exposed to petroleum-based fluids. With its quick response time typically around 50 ms and minimal leakage at high pressures (5 in\u00b3/min at 3000 psi), the DMDADPN71299 is an effective solution for various hydraulic control applications requiring precise flow management and reliable operation under high-pressure conditions.
