The Sun Hydraulics DNCAMAV72419 (DNCAMAV72419) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool mechanism. This directional valve is designed with a closed transition between positions to significantly reduce oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve operates optimally with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly of this model is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. Notably, the valve requires no minimum hydraulic pressure for operation due to its direct actuation design. The DNCAMAV72419 employs a wet armature design where the working fluid surrounds the armature, exposing it to coil-generated heat. This feature can impact long-term operation if the coil remains energized for extended periods, especially with fluids like water-glycol mixtures that may degrade and form varnishes affecting functionality. The valve offers various coil termination and voltage options, including configurations with surge protection. Its high-efficiency solenoid provides substantial spool actuating force per watt, promoting dependable valve shifting. This model incorporates Sun's floating style construction to minimize internal part binding from installation torque or cavity machining variations. It fits within cavity T-31A of Series 1 and boasts a capacity of 8 gpm (30 L/min) with maximum leakage at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Additional features include interchangeable coils compatible with other Sun Series 1 products and manual override capabilities requiring minimal force for operation. With a robust design suited for high-frequency switching up to 15,000 cycles per hour, this versatile cartridge valve meets a wide range of hydraulic system requirements.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
