The Sun Hydraulics DMDATRV928 (DMDATRV928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed to control the direction of hydraulic flow in advanced fluid power systems. This direct-acting, balanced spool directional valve features a robust design with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. The valve offers precise control with closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times especially in pilot control applications where flow capacity is less critical. The DMDATRV928 operates without requiring a minimum hydraulic pressure, facilitating its use in various applications. It includes options for manual override controls (D, L, T types), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Notably, the valve incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. This model employs a wet armature design where the working fluid surrounds the armature. This setup can influence fluid integrity if the coil remains energized excessively, potentially leading to breakdowns in certain fluid types like water-glycol mixtures. The valve's design also features interchangeable coils compatible with other Sun Series 1 solenoid products and includes Sun\u2019s floating style construction to minimize internal part binding caused by installation torque or machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response times of 50 ms. The DMDATRV928 supports switching frequencies up to 15,000 cycles per hour and has manual override requirements detailed for operational ease. This compact yet robust model weighs approximately 0.60 lb (0.30 kg) and adheres strictly to quality standards ensuring optimal performance in demanding hydraulic setups.
