The Sun Hydraulics DMDALAV624 (DMDALAV624) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve is engineered to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The DMDALAV624 features a fatigue-rated solenoid tube assembly suitable for demanding environments. Key attributes include its closed transition spools (B and R), which remain closed during position changes to enhance performance at the cost of reduced flow capacity, making it ideal for pilot control applications where rapid and consistent response times are critical. The valve operates without requiring a minimum hydraulic pressure, facilitating versatile use across various hydraulic systems. Additionally, the DMDALAV624 incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature, which can affect fluid integrity under prolonged energization. The model is also compatible with other Sun Series 1 solenoid products concerning coil interchangeability and can be mounted in either direction on the tube. This model employs Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It has a typical response time of 50 ms and supports up to 15,000 switching cycles per hour. Manual override features require minimal force and offer precise control through a short stroke. The robust construction and thoughtful engineering make the DMDALAV624 an excellent choice for specialized hydraulic applications requiring reliable directional control and fast response times.

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.
