The Sun Hydraulics DMDATRN928 (DMDATRN928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve offers closed transitions between positions B and R, which enhances performance by ensuring faster and more consistent response times, particularly useful in pilot control setups where capacity is less critical. The DMDATRN928 operates without requiring a minimum hydraulic pressure, which allows for versatile deployment in various hydraulic systems. It includes options such as manual overrides with detent mechanisms (D or L control) designed for temporary actuation; these controls are rated for approximately 7,000 cycles. The model is compatible with EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances to avoid damage. This valve utilizes a wet armature design where the working fluid surrounds the armature. This setup might lead to higher fluid temperatures if the coil remains energized over extended periods, potentially affecting fluid integrity and valve performance. Interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in use, accommodating different system requirements without additional modifications. Additional features include Sun's floating style construction that minimizes internal parts binding due to installation variances or excessive torque, ensuring reliable operation and longevity. The valve supports up to 12 gpm (45 L/min) flow capacity and has a quick typical response time of around 50 ms. Moreover, it is engineered to handle switching frequencies up to 15,000 cycles per hour with minimal leakage, demonstrating its capability for high-duty applications.
