The Sun Hydraulics DMDAMNV72419 (DMDAMNV72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve boasts a robust design with a fatigue rating for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. It features closed transitions between spool positions B and R to enhance performance limits while sacrificing some capacity, making it ideal for pilot control applications where rapid and consistent response times are critical. The DMDAMNV72419 operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power applications. It incorporates manual override options with detent mechanisms designed for temporary actuation, which have a mechanical life expectancy of about 7,000 cycles. Special attention is needed regarding seal compatibility; cartridges equipped with EPDM seals should only be used with phosphate ester fluids to avoid damage from petroleum-based substances. This model uses a wet armature design allowing the working fluid to surround the armature which may affect fluid integrity over prolonged energization periods due to heat exposure. The valve's construction includes Sun\u2019s floating style which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Additionally, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Key specifications include a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The DMDAMNV72419 also supports switching frequencies up to 15,000 cycles/hr and has manual override features that require minimal force. This compact and efficient valve is an excellent choice for advanced hydraulic systems requiring reliable directional control and swift actuation.

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.
