The Sun Hydraulics DMDADBN72419 (DMDADBN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient performance in hydraulic systems. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. The valve's design includes closed transitions between Spools B and R, enhancing its performance limits while sacrificing some capacity. This makes it particularly suitable for pilot control applications where speed and consistency of response are more critical than flow capacity. Additionally, the DMDADBN72419 operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power applications. Equipped with EPDM seals, the valve is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as this can damage the seals. The wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used due to potential breakdown at high temperatures. This model also features interchangeable coils with other Sun Series 1 solenoid products and incorporates a floating style construction that minimizes internal parts binding. The manual override mechanism in models with D or L control is intended for temporary actuation and has a mechanical life expectancy of around 7,000 cycles. With a flow capacity of up to 12 gpm (45 L/min) and quick response times typically around 50 ms, the Sun Hydraulics DMDADBN72419 offers an effective solution for directing flow in hydraulic circuits requiring precise control and rapid actuation.

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.
