The Sun Hydraulics DMDATBV824 (DMDATBV824) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve boasts a fatigue rating for 5000 psi (350 bar) service, making it robust for demanding applications. The DMDATBV824 features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable as pilot controls where capacity is less critical. This model is directly actuated and operates without a minimum hydraulic pressure requirement. It includes manual overrides with detent mechanisms designed primarily for temporary actuation; these mechanisms have a mechanical life expectancy of about 7,000 cycles. The valve is compatible with EPDM seals specifically for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design of the DMDATBV824 ensures that the working fluid surrounds the armature which may be subject to heat during prolonged coil energization. This aspect needs consideration particularly when using water-glycol mixtures that can degrade under heat. For flexible installation options, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this model incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a capacity of 12 gpm (45 L/min) and a maximum operating pressure of 5000 psi (350 bar), along with a typical response time of 50 ms and maximum leakage at 3000 psi rated at 5 in\u00b3/min., the DMDATBV824 is engineered to meet rigorous industrial demands while ensuring reliability and efficiency in hydraulic system operations.

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.
