The Sun Hydraulics DMDATPV624N (DMDATPV624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures precise control with its closed transition spools (B and R), which remain closed during the switch between positions to offer consistent and rapid response times, particularly suitable for pilot control applications where capacity is less critical. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDATPV624N is engineered to handle demanding tasks efficiently. The valve features a fatigue-rated solenoid tube assembly for extended service life under high-pressure conditions. It requires no minimum hydraulic pressure for operation, making it versatile across various hydraulic systems. This model incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over long periods due to heat exposure. Therefore, it's crucial to consider the type of fluid used; EPDM seals are recommended for systems with phosphate ester fluids but should avoid contact with petroleum-based substances which can degrade the seals. Additional durability is provided by Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations in cavity/cartridge setups. The manual override feature included in models with D, L, or T controls offers temporary actuation with a mechanical life expectancy of about 7,000 cycles. Interchangeable coils compatible with other Sun Series 1 solenoid products add flexibility to maintenance and replacement processes, ensuring that this valve can be adapted or repaired with relative ease while maintaining operational integrity across various installations.

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.
