The Sun Hydraulics DMDALNV72499 (DMDALNV72499) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility in various applications. The model features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for rigorous industrial operations. The valve's design incorporates closed transitions between Spools B and R, optimizing response times and consistency crucial for pilot control applications where capacity is less critical. It also includes a manual override with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles of mechanical life. This model uses EPDM seals specifically for systems containing phosphate ester fluids; however, these seals are sensitive to petroleum-based substances which can cause damage. Another notable feature of the DMDALNV72499 is its wet armature design that allows the working fluid to surround the armature, although prolonged exposure to heat when the coil is energized could affect fluid integrity over time. The interchangeable coils with other Sun Series 1 solenoid products offer additional flexibility and ease of maintenance. This valve also benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. With a typical response time of 50 ms and a capacity of 12 gpm (45 L/min), this model ensures efficient operation under high switching frequencies up to 15,000 cycles/hr. The precise engineering and robust construction of the DMDALNV72499 make it a reliable choice for demanding hydraulic control 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.
