The Sun Hydraulics DMDATBV248 (DMDATBV248) 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 hydraulic operations. It features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The valve incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. Equipped with EPDM seals, the DMDATBV248 is optimized for use with phosphate ester fluids, while its exposure to petroleum-based fluids should be avoided to prevent seal damage. The wet armature design of the valve helps in cooling but requires consideration of fluid characteristics as prolonged exposure to heat might degrade certain types of hydraulic fluids. This model boasts interchangeable coils with other Sun Series 1 solenoid products, offering flexibility in maintenance and replacement processes. Additionally, it features Sun's floating style construction which minimizes internal parts binding \u2014 a common issue caused by excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDATBV248 ensures efficient fluid control in hydraulic systems. Its quick response time (typical 50 ms), combined with a maximum switching frequency of 15000 cycles per hour, makes it an ideal choice for applications requiring frequent and precise operation adjustments. The manual override feature necessitates minimal force, making temporary actuation straightforward during system troubleshooting or setup adjustments.

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.
