The Sun Hydraulics DMDATBV548 (DMDATBV548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise fluid control in hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve's spool transitions between positions B and R are closed, enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The DMDATBV548 requires no minimum hydraulic pressure to operate and incorporates a wet armature design. The surrounding working fluid can absorb the heat generated by the coil, which is an important consideration for system design, particularly when the valve is energized over extended periods. This model supports flow rates up to 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It also features interchangeable coils with other Sun Series 1 solenoid products, offering flexibility in maintenance and system upgrades. Equipped with EPDM seals, the DMDATBV548 is specifically configured for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Manual override options include detent mechanisms designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Additionally, this model benefits from Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations.

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.
