The Sun Hydraulics DMDADRV299 (DMDADRV299) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve operates effectively with no minimum hydraulic pressure required for functioning. The solenoid tube assembly of the valve is fatigue rated for robust 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. Key features of the DMDADRV299 include closed transitions between spools B and R, which enhance performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve also incorporates a wet armature design, allowing the working fluid to surround the armature which can be crucial when considering the type of fluid used due to potential breakdowns at high temperatures. For manual operation, the model equipped with D or L control includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction to minimize internal parts binding. The cartridge is configured to work with EPDM seals specifically for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. With a maximum operating pressure of 5000 psi and a capacity of 12 gpm (45 L/min), along with quick response times typically around 50 ms, this valve is an efficient choice for various hydraulic applications 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.
