The Sun Hydraulics DMDALAV724 (DMDALAV724) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, well-suited for demanding hydraulic applications requiring robust control and reliability. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, enhancing its versatility in various system configurations. It features a fatigue-rated solenoid tube assembly designed to withstand pressures up to 5000 psi (350 bar), making it an excellent choice for high-pressure environments. The DMDALAV724 is equipped with closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The valve's manual override options include the D or L control with a detent mechanism intended for temporary actuation, supporting mechanical life expectancy of around 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended. The valve also incorporates a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when dealing with long energization periods as it affects fluid integrity over time. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Structurally, the valve benefits from Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and swift typical response times of 50 ms, this valve ensures efficient operation and control precision in 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.
