The Sun Hydraulics DMDAMAV724 (DMDAMAV724) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that is designed for direct-acting operation with a balanced spool directional control. This robust valve features a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. It operates without requiring a minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. The DMDAMAV724 is equipped with a wet armature design, where the working fluid surrounds the armature, which is crucial for heat management when the coil is energized for extended periods. This design consideration is particularly important when using water-glycol mixtures as they can degrade at high temperatures. The valve's manual override option includes a detent mechanism intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Additionally, this model uses EPDM seals specifically designed for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. The construction of the DMDAMAV724 incorporates Sun's floating style which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient and reliable performance in controlling fluid flow within hydraulic systems.

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.
