The Sun Hydraulics DMDATAV299 (DMDATAV299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for demanding applications, ensuring reliability and durability. The DMDATAV299 valve incorporates closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, ideal for pilot control applications where capacity is less critical. Its design requires no minimum hydraulic pressure to operate, making it versatile for various hydraulic systems. The model includes manual override options with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles of mechanical life expectancy. Equipped with EPDM seals, the DMDATAV299 is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design allows the working fluid to surround the armature which could be subjected to heat during prolonged coil energization\u2014a consideration when using certain fluid types that may degrade under heat. This valve also features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction includes Sun's floating style design to minimize internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. With its robust build and versatile application potential, the DMDATAV299 is an excellent choice for sophisticated hydraulic systems requiring precise control and reliability.

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.
