The Sun Hydraulics DMDAMPV72419 (DMDAMPV72419) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features a unique closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications as pilot controls where capacity is less critical. The DMDAMPV72419 incorporates advanced design elements such as a fatigue-rated solenoid tube assembly and wet armature design. The wet armature setup helps in cooling but requires consideration of fluid type as certain fluids may degrade under prolonged exposure to heat. It is compatible with EPDM seals for systems using phosphate ester fluids, though these seals must avoid contact with petroleum-based substances which could cause damage. Additionally, the cartridge valve offers flexibility in manual operation with a detent mechanism designed for temporary actuation and an expected mechanical life of approximately 7,000 cycles. For ease of integration into various systems, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in any direction on the tube. This model also benefits from Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With its robust construction and versatile design features, the Sun Hydraulics DMDAMPV72419 valve is an ideal choice for demanding hydraulic applications requiring precise control 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.
