The Sun Hydraulics DMDAXRV72419 (DMDAXRV72419) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is capable of handling 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 robust design with interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either direction for flexible installation. The DMDAXRV72419 uses a wet armature design, allowing the working fluid to surround the armature which helps in heat dissipation but requires careful selection of fluid to prevent breakdown and varnish formation. It incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This model is also equipped with EPDM seals suitable for use with phosphate ester fluids, though exposure to petroleum-based fluids should be avoided as it can damage the seals. This valve is particularly effective when used as pilot controls thanks to its closed transition between spools B and R, ensuring faster and more consistent response times without the need for minimum hydraulic pressure. The manual override feature included in models with D or L control is intended for temporary actuation, supporting mechanical life expectancy of approximately 7,000 cycles. Additionally, the model boasts quick response times typically around 50 ms and supports a high switching frequency up to 15,000 cycles per hour. Overall, the Sun Hydraulics DMDAXRV72419 offers an excellent combination of performance, durability, and versatility suitable for various applications requiring reliable directional control in hydraulic systems.

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.
