The Sun Hydraulics DMDALAV924 (DMDALAV924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting operation with a balanced spool directional control. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. The valve operates efficiently without minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. This model incorporates closed transitions between Spools B and R, optimizing performance by allowing faster and more consistent response times, especially beneficial when used as pilot controls where flow capacity is less critical. The manual override feature in models with D or L control is specifically designed for temporary actuation, supported by a mechanical life expectancy of about 7,000 cycles. Equipped to handle phosphate ester fluids thanks to its EPDM seals configuration, the DMDALAV924 should not be exposed to petroleum-based fluids which could damage the seals. Another key feature is its wet armature design; the working fluid surrounds the armature which can be crucial if the coil remains energized over extended periods. This design consideration helps prevent breakdown and varnishing of certain fluids like water-glycol mixtures at high temperatures. For ease of integration and maintenance, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction also includes Sun's floating style to minimize internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating capacity of 12 gpm (45 L/min) and a quick typical response time of 50 ms, along with interchangeable seal kits for different environmental requirements, this valve stands out as a reliable choice for dynamic hydraulic system applications requiring precise control and durability.

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.
