The Sun Hydraulics DMDATAV72419 (DMDATAV72419) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. It features a direct-acting, balanced spool with closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, making it versatile in various hydraulic circuits. With a robust design rated for up to 5000 psi (350 bar), this valve is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. The wet armature design of the valve ensures that the working fluid surrounds the armature which can be beneficial or detrimental depending on the duration the coil remains energized and the type of fluid used. The DMDATAV72419 also features interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. Additionally, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum switching frequency of 15000 cycles per hour. The manual override mechanism requires a force of about 5 lbs at 1000 psi to actuate and has a stroke length of .10 inches (2.5 mm). This model weighs approximately .60 lb (0.30 kg) and adheres to stringent performance standards ensuring reliability and durability in demanding 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.
