The Sun Hydraulics DMDATBV299 (DMDATBV299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate seamlessly without the need for minimum hydraulic pressure, enhancing its efficiency and responsiveness across various applications. The valve features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure operations. The DMDATBV299 incorporates closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls. With a flow capacity of up to 12 gpm (45 L/min) and capable of handling maximum operating pressures up to 5000 psi (350 bar), this valve is designed to meet rigorous industrial demands. It also features interchangeable coils with other Sun Series 1 solenoid products, adding versatility and ease of maintenance to its design. Further enhancing its utility, the valve includes manual override options with a detent mechanism intended for temporary actuation; these are expected to last approximately 7,000 cycles. The model also uses EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids which can degrade the seals. Additionally, the wet armature design helps manage heat dissipation but requires consideration of fluid compatibility over extended periods. This product\u2019s construction benefits from Sun's floating style design that minimizes internal parts binding due to installation torque or machining variations. Each unit weighs about 0.60 lb (0.30 kg) and requires an installation torque between 30 - 35 lbf.ft (41 - 47 Nm), ensuring secure and reliable integration into hydraulic systems.

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.
