The Sun Hydraulics DMDALAV299 (DMDALAV299) is a solenoid-operated 3-way, 2-position cartridge valve that offers precision control in hydraulic systems. Designed as a direct-acting, balanced spool directional valve, it operates without the need for minimum hydraulic pressure, enhancing its versatility across various applications. This model features a fatigue rating for up to 5000 psi (350 bar), making it suitable for high-pressure environments. With a response time typically around 50 ms and capable of handling up to 12 gpm (45 L/min), the DMDALAV299 ensures swift and reliable operation. The valve's design includes closed transitions between spool positions B and R, which optimizes performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The manual override function incorporated into this model is specifically designed with a detent mechanism intended for temporary actuation, supporting around 7,000 cycles mechanically. It also features EPDM seals suitable for use with phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. This model benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it employs Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With its robust build and advanced engineering, the DMDALAV299 is an excellent choice for systems requiring reliable directional control of fluid flow under varying 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.
