The Sun Hydraulics DMDAMNV724 (DMDAMNV724) is a high-performance solenoid-operated 3-way, 2-position cartridge valve engineered for precise hydraulic control. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure, enhancing its reliability and performance in various applications. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability under demanding conditions. The valve's spools B and R maintain a closed position during transitions between two positions, which limits flow capacity but significantly enhances performance by providing faster and more consistent response times. This characteristic makes the DMDAMNV724 particularly suitable for pilot control applications where capacity is less critical than response speed. Equipped with EPDM seals, the DMDAMNV724 is compatible 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 allows the working fluid to surround the armature, potentially affecting function if exposed to heat for prolonged periods\u2014something to consider when using certain hydraulic fluids. This model also incorporates interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it uses Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Other technical specifications include a maximum operating pressure of 5000 psi (350 bar), a flow capacity of 12 gpm (45 L/min), and fast typical response times of around 50 ms. The manual override feature requires minimal force and is intended for temporary actuation only, supporting around 7,000 cycles mechanically. This makes the DMDAMNV724 an adaptable solution for various hydraulic systems requiring robust and precise control.

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.
