The Sun Hydraulics DMDATRV924 (DMDATRV924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve engineered for direct-acting control with a balanced spool design. This valve features a fatigue rating of 5000 psi for robust operation in demanding applications. The DMDATRV924 is specifically designed to ensure closed spools B and R during transitions, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile across various hydraulic systems. It incorporates manual override options with the detent mechanism designed for temporary actuation, supporting mechanical life expectancy up to approximately 7,000 cycles. The DMDATRV924 uses EPDM seals suitable for phosphate ester fluids while avoiding exposure to petroleum-based substances which could degrade the seals. A notable feature of this model is its wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged coil energization. This model supports interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting orientation. Additional attributes include a maximum flow capacity of 12 gpm (45 L/min), quick typical response times of around 50 ms, and a switching frequency capable of handling up to 15,000 cycles per hour. Leakages are minimal at high pressures, ensuring efficient operation. It also features Sun's floating style construction that minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge setup, specified as T11A cavity type within Series 1. The manual override requires minimal force and has a short stroke length for ease of operation while maintaining tight control over system parameters.
