The Sun Hydraulics DMDALPV71219 (DMDALPV71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. The valve's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times particularly in pilot control applications where capacity is less critical. Equipped with EPDM seals, the DMDALPV71219 cartridge is specifically configured for use with phosphate ester fluids; however, it is important to avoid exposure to petroleum-based fluids which can damage the seals. Another key feature of this model is its wet armature design that allows the working fluid to surround the armature, thereby directly influencing the heat management when the coil is energized over long durations. This model supports a maximum flow capacity of 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It has quick response times typically around 50 ms and maintains low leakage rates under high pressure. Additionally, it offers interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal binding risks due to installation torque or cavity/cartridge machining variations. The manual override mechanism provided in models with D or L control is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve also supports switching frequencies up to 15,000 cycles per hour, making it suitable for high-cycle applications requiring precision and reliability.

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.
