The Sun Hydraulics DMDADPV712 (DMDADPV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its utility in various applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding environments. The DMDADPV712 employs a wet armature design where the working fluid surrounds the armature, which is beneficial for heat dissipation but requires careful consideration of fluid type to avoid breakdown and varnish formation. This model is equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, and can be mounted in either direction on the tube. It offers a manual override option with a detent mechanism intended for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. The valve is configured to minimize internal parts binding through Sun\u2019s floating style construction which accounts for installation torque and machining variations. Notably, the DMDADPV712 has specific requirements regarding seal materials; cartridges configured with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based fluids will damage these seals. This model has a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Its response time is typically around 50 ms, and it supports switching frequencies up to 15,000 cycles per hour. Additional features include a manual override force requirement of approximately 5 lbs at 1000 psi for port 1 and a manual override stroke of .10 inches (2.5 mm). This compact yet robust valve weighs about .60 lb (0.30 kg) and ensures reliable performance in hydraulic circuit applications where precision and durability are crucial.
