The Sun Hydraulics DMDATPV948 (DMDATPV948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust and efficient performance in various hydraulic applications. Featuring a fatigue rating for 5000 psi (350 bar) service, the DMDATPV948 ensures reliable operation under high-pressure conditions. The valve's spools B and R maintain a closed state during transitions between positions, optimizing performance by providing faster and more consistent response times, especially in pilot control applications where capacity is less critical. The DMDATPV948 operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. It includes options for manual overrides with detent mechanisms designed for temporary actuation; these are particularly useful in emergency or specific operational scenarios. With an estimated mechanical life of about 7,000 cycles for the manual control assembly, this valve promises durability and reliability. Configurations of the cartridge with EPDM seals are suitable for systems using phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The wet armature design of the valve allows the working fluid to surround the armature, which can be a consideration if the coil remains energized over extended periods as it may influence fluid integrity. Additionally, coils used in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate varying installation requirements. The design incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. This model supports up to 12 gpm (45 L/min) capacity and offers rapid response times typical at 50 ms.
