The Sun Hydraulics DMDALBN72419 (DMDALBN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is characterized by its robust construction and capability to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDALBN72419 operates without requiring a minimum hydraulic pressure, which allows for flexible usage across various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation. The mechanical life expectancy of the manual control assembly in this model reaches up to approximately 7,000 cycles, ensuring durability and reliability in operation. Equipped with EPDM seals, this cartridge valve is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Its wet armature design means that the working fluid surrounds the armature which might be susceptible to heat if the coil remains energized over extended periods. Additionally, this model incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. The interchangeable coils compatible with other Sun Series 1 solenoid products provide added versatility and ease of maintenance. With its compact size and a weight of only .60 lb (0.30 kg), the DMDALBN72419 offers an efficient solution for directing flow within hydraulic circuits while maintaining stringent performance standards.

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.
