The Sun Hydraulics DMDADBV748 (DMDADBV748) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve's spool transitions between positions B and R are closed, enhancing performance by providing faster and more consistent response times particularly suitable for pilot control applications where capacity is less critical. This versatile model requires no minimum hydraulic pressure to operate and includes an option for manual override through the D or L control detent mechanism, primarily intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature, potentially impacting fluid integrity if exposed to prolonged coil energization. It is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. Additionally, the DMDADBV748 incorporates interchangeable coils with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction which minimizes internal parts binding caused by installation torque or machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and swift typical response times of 50 ms, this valve is engineered to meet rigorous industrial requirements efficiently. Essential specifications include a maximum operating pressure of 5000 psi (350 bar), switching frequency up to 15,000 cycles/hr., and minimal leakage at high pressures ensuring reliable operation under various conditions.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
