The Sun Hydraulics DNCAMTV72419 (DNCAMTV72419) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting applications. This balanced spool directional valve features a closed transition between positions, which minimizes oil loss during shifting, making it particularly beneficial for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to performance limitations. With a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), this valve operates without requiring minimum hydraulic pressure. It incorporates EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based substances can damage these seals. The design includes a wet armature, where the working fluid surrounds and cools the armature, an important consideration when the coil is energized for extended durations. Certain fluids like water-glycol mixtures may degrade at high temperatures over time. The valve offers various coil termination and voltage options with or without surge protection and features interchangeable coils compatible with other Sun Series 1 solenoid products. It boasts a high-efficiency magnetic design that delivers significant spool actuating force per watt, ensuring reliable operation. This model can handle capacities up to 8 gpm (30 L/min) and maximum operating pressures of 5000 psi (350 bar), with typical response times around 50 ms. It maintains low leakage rates of up to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Designed for durability and precision, it supports switching frequencies up to 15,000 cycles per hour and includes manual override capabilities requiring minimal force. The Sun floating style construction reduces risks of internal binding from installation torque or machining variations.

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.
