The Sun Hydraulics DMDATRV724N (DMDATRV724N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. Designed as a direct-acting, balanced spool directional valve, it features a robust construction that is fatigue rated for 5000 psi (350 bar) service, ensuring reliability in demanding applications. The valve's solenoid tube assembly enhances its durability and performance under high-pressure conditions. A key characteristic of the DMDATRV724N is its closed transition between Spools B and R, which optimizes performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, facilitating versatile application in various hydraulic systems. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, which could be a consideration if the coil remains energized for extended periods due to potential breakdowns in certain fluid types. The DMDATRV724N also features interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal parts binding. This design consideration helps prevent operational issues that might arise due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve is an efficient solution for controlling flow in hydraulic systems. It supports a maximum switching frequency of 15,000 cycles/hr and has manual override capabilities designed for temporary actuation with an expected mechanical life of around 7,000 cycles. This makes the DMDATRV724N both a versatile and reliable choice for specialized hydraulic 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.
