The Sun Hydraulics DMDAXNV72419 (DMDAXNV72419) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, including a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The valve features closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times during operation. This design choice benefits pilot control applications where capacity is less critical. The DMDAXNV72419 operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes manual override options with a mechanical life expectancy of approximately 7,000 cycles, depending on the model variant equipped with either D or L control mechanisms. The valve's wet armature design allows the working fluid to surround the armature which can be critical when considering the type of fluid used due to potential breakdowns from prolonged exposure to heat. For compatibility with different system fluids, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as it could damage the seals. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation variances or machining discrepancies. With a maximum operating pressure of 5000 psi and a flow capacity up to 12 gpm (45 L/min), along with rapid response times typically around 50 ms and switching frequencies up to 15,000 cycles/hr., the DMDAXNV72419 is engineered for both reliability and high-efficiency performance in complex hydraulic setups.

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.
