The Sun Hydraulics DMDAMAV72419 (DMDAMAV72419) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design that ensures reliable control of hydraulic flow with precise actuation. Engineered for robustness, the valve operates without requiring a minimum hydraulic pressure, making it suitable for a variety of applications including those with low-pressure environments. This model boasts a fatigue rating of 5000 psi (350 bar), making it ideal for demanding applications. The incorporation of B and R closed spools during transition enhances performance by providing faster and more consistent response times, particularly beneficial in pilot control setups where capacity is less critical. Additionally, the valve supports interchangeable coils from other Sun Series 1 solenoid products, which can be mounted in either direction to accommodate different system configurations. The DMDAMAV72419 also features a wet armature design; this design choice means that the working fluid surrounds the armature\u2014important to consider in applications where the coil may be energized for extended periods as heat transfer could affect fluid integrity. For systems using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. Manual override options with detent mechanisms are available for temporary actuation, supporting approximately 7,000 cycles mechanically. The product's construction includes Sun's floating style which minimizes internal part binding due to installation variances or machining discrepancies. Overall, the DMDAMAV72419 is engineered to provide efficient and reliable performance in hydraulic systems requiring precise directional control and rapid response times under various operating conditions.

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.
