The Sun Hydraulics DMDATPV812 (DMDATPV812) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. The valve is characterized by its closed transitions between Spools B and R, which enhance performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is not a critical factor. This model operates without the need for minimum hydraulic pressure and incorporates a wet armature design where the working fluid surrounds the armature. This characteristic is crucial for applications where the coil may be energized for extended periods, although care must be taken with certain fluids that might degrade under prolonged heat exposure. The DMDATPV812 also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Notably, this valve employs Sun's floating style construction to minimize internal parts binding due to excessive installation torque and/or variations in cavity/cartridge machining. It features manual override options with a detent mechanism designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles when equipped with D, L, or T manual control assemblies. The use of EPDM seals in specific configurations indicates suitability for systems utilizing phosphate ester fluids while advising against exposure to petroleum-based substances. Additional technical specifications include a flow capacity of up to 12 gpm (45 L/min), a typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and manual override requirements that ensure ease of use under varying pressure conditions. This model\u2019s robust design and versatile features make it an essential component for efficient hydraulic system management across multiple settings.
