The Sun Hydraulics DMDALBV299 (DMDALBV299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures precise operation with no minimum hydraulic pressure required for functionality. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding environments. The DMDALBV299 incorporates closed transitions between spool positions B and R, enhancing performance limits while sacrificing some capacity\u2014a trade-off that benefits applications requiring fast and consistent response times over high flow rates. This design is particularly advantageous when used as pilot controls. Additionally, the valve\u2019s manual override feature includes a detent mechanism intended for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. Configured with EPDM seals, this model is specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, which should be considered in applications where the coil may be energized continuously. The valve also supports interchangeable coils with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction to minimize internal binding due to installation torque or machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDALBV299 provides efficient fluid control in hydraulic systems. Its robust construction and thoughtful design elements make it a reliable choice for specialized hydraulic applications requiring precise directional control and durability under high-pressure conditions.

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.
