The Sun Hydraulics DMDATBV228 (DMDATBV228) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting operation with a balanced spool. This model is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, making it suitable for rigorous industrial applications. The valve features a closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times particularly in pilot control applications where capacity is less critical. The DMDATBV228 operates without requiring a minimum hydraulic pressure, which allows for flexibility in various system designs. It includes options for manual override controls designated as D, L, or T types, with a mechanical life expectancy of about 7,000 cycles. The manual override is designed primarily for temporary actuation. This model incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids as exposure can cause damage. The wet armature design of the valve ensures that the working fluid surrounds the armature which may be relevant when considering fluid types that degrade at higher temperatures due to prolonged coil energization. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing coils to be mounted in either direction on the tube. The design also benefits from Sun's floating style construction which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With additional specifications like a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), the Sun Hydraulics DMDATBV228 is tailored for precise fluid control in high-pressure applications across various hydraulic systems.
