The Sun Hydraulics DMDADNV624 (DMDADNV624) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for various hydraulic applications. This direct-acting, balanced spool directional valve is specifically engineered to operate without minimum hydraulic pressure, enhancing its reliability and performance across a range of operating conditions. The valve boasts a robust design with a fatigue rating for 5000 psi (350 bar) service, ensuring durability and long-term functionality in demanding environments. Equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, the DMDADNV624 offers flexibility in maintenance and replacement processes. It features a wet armature design where the working fluid surrounds the armature, which is crucial for applications where the coil may be energized for extended periods. However, users should note that certain fluids may degrade under prolonged exposure to heat, potentially affecting performance. This model incorporates Sun's floating style construction to minimize internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This feature contributes to consistent operational reliability and precision. The valve's manual override mechanism is designed primarily for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The DMDADNV624 supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It also offers rapid response times typical at 50 ms and maintains control over leakage with maximum valve leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The switching frequency capability reaches up to 15,000 cycles/hr, making it suitable for high-cycle applications requiring precise control and fast response.

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.
