The Sun Hydraulics DMDALAN299 (DMDALAN299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. Featuring a direct-acting, balanced spool design, this valve ensures precise control and reliable operation without the need for minimum hydraulic pressure. The DMDALAN299 is built to handle maximum operating pressures up to 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min), making it suitable for a wide range of medium to high-pressure applications. The valve's construction includes a fatigue-rated solenoid tube assembly, ensuring durability even under demanding conditions. It incorporates Sun's floating style construction which minimizes internal parts binding, a common issue in valves due to excessive installation torque or cavity/cartridge machining variations. The spools B and R maintain closed positions during transitions, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. Additionally, the DMDALAN299 features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube for flexible installation options. It also uses EPDM seals specifically designed for compatibility with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For manual override operations, the valve includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This model also supports easy maintenance with available Viton seal kits specific to cartridge and coil components. With its robust design and versatile features, the Sun Hydraulics DMDALAN299 valve is an excellent choice for enhancing system performance in various hydraulic applications.

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.
