The Sun Hydraulics DMDADPN748 (DMDADPN748) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is capable of handling maximum operating pressures up to 5000 psi (350 bar), making it suitable for a wide range of demanding applications. The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. The DMDADPN748 operates without the need for minimum hydraulic pressure, ensuring reliable functionality under various conditions. It includes options for manual override controls (D, L, T) with a mechanical life expectancy of approximately 7,000 cycles. The model is also compatible with EPDM seals for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the valve incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods as it impacts fluid integrity due to heat exposure. For versatility in system design, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Engineered with Sun\u2019s floating style construction, the DMDADPN748 minimizes internal parts binding which could result from excessive installation torque or cavity/cartridge machining variations. This feature ensures smoother operation and increased durability of the valve. With a flow capacity of 12 gpm (45 L/min) and typical response times of 50 ms, this model meets rigorous industrial requirements while maintaining efficient performance levels.
