The Sun Hydraulics DMDATNV724N (DMDATNV724N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design which ensures reliable operation without the need for minimum hydraulic pressure. This valve is particularly suited for applications requiring precise control with its fast and consistent response times facilitated by the closed transition between spool positions. The DMDATNV724N operates efficiently under a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). This model is built with durability in mind, featuring fatigue-rated solenoid tube assemblies for demanding 5000 psi service environments and a mechanical life expectancy of about 7,000 cycles in models equipped with manual control assemblies (D, L, T). The wet armature design helps manage heat dissipation but requires careful selection of fluid types to avoid breakdowns and varnish formation that could impair function. Specifically configured EPDM seals are recommended for use with phosphate ester fluids to prevent damage from petroleum-based products. Additionally, the interchangeability of coils with other Sun Series 1 solenoid products adds versatility in maintenance and replacement processes. The valve also incorporates Sun\u2019s floating style construction which minimizes internal parts binding \u2014 a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This ensures smoother operation and extends the operational lifespan of the unit. With its robust construction and advanced engineering, the DMDATNV724N is an ideal choice for systems requiring reliable directional control in high-pressure applications.

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.
