The Sun Hydraulics DMDADPN72419 (DMDADPN72419) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar), making it suitable for high-pressure operations. The valve operates efficiently with no minimum hydraulic pressure required for activation, ensuring reliable performance across a range of conditions. Equipped with closed transitions between Spools B and R, the DMDADPN72419 enhances performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. This model also features interchangeable coils with other Sun Series 1 solenoid products, providing flexibility and ease of maintenance. The wet armature design of the valve allows the working fluid to surround the armature which could be a consideration in systems where the coil remains energized for extended periods. For manual override operations, this model includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. It also incorporates Sun\u2019s floating style construction to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The DMDADPN72419 supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity up to 12 gpm (45 L/min). Its response time is typically around 50 ms, and it can handle switching frequencies up to 15,000 cycles per hour. This model uses Viton seals for the cartridge and coil seal kits, ensuring compatibility with phosphate ester fluids while avoiding exposure to petroleum-based fluids which could damage the seals. Overall dimensions include a solenoid tube diameter of .75 inches (19 mm) and it requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm).

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.
