The Sun Hydraulics DMDAXAV72419 (DMDAXAV72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its responsiveness and reliability across a range of operating conditions. It features spools B and R that are closed during transitions between positions, optimizing performance by ensuring faster and more consistent response times especially suitable for pilot controls where capacity is less critical. The valve's construction includes a wet armature design, meaning the working fluid surrounds the armature which can be exposed to heat when the coil is energized for prolonged periods. This design consideration is crucial when using specific fluids like water-glycol mixtures that may degrade under high temperatures. Additionally, it incorporates Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), this valve ensures robust performance in demanding environments. The manual override feature with a detent mechanism is designed for temporary actuation and has an estimated mechanical life of approximately 7,000 cycles. The DMDAXAV72419 also offers interchangeability with other Sun Series 1 solenoid products regarding coils, which can be mounted in either direction to suit different installation requirements. Moreover, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage the seals. The versatility and durable construction of the DMDAXAV72419 make it an effective solution for directing flow precisely where needed 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.
