The Sun Hydraulics DMDADNV724 (DMDADNV724) 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 features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The valve's design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. Equipped with either D or L manual override controls, the DMDADNV724 offers temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve is also compatible with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve means that the working fluid surrounds the armature which could affect performance if the coil remains energized for extended periods. This model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of about 50 ms, and a switching frequency up to 15,000 cycles/hr. The manual override requires a force of about 5 lbs at 1000 psi per Port 1 and has a stroke length of .10 inches (2.5 mm). The overall weight of the model is approximately .60 lb (0.30 kg).

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.
