The Sun Hydraulics DNCALSV72419 (DNCALSV72419) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, which reduces oil loss during shifting\u2014an essential attribute for pilot control circuits. It is optimized for use with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it may not perform optimally and is not recommended. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure applications. Notably, this valve requires no minimum hydraulic pressure to operate due to its direct actuation design. The DNCALSV72419 employs a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil. Users should be cautious of fluid types like water-glycol mixtures that can degrade over time when exposed to high temperatures. This valve offers various coil termination and voltage options, with or without surge protection, facilitating versatile integration into different systems. Its high-efficiency solenoid delivers substantial spool actuating force per watt expended, ensuring reliable performance. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The coil connectors are rated up to IP69K for enhanced environmental protection, with additional weatherized options available. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. The valve's specifications include an 8 gpm (30 L/min) capacity, a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and minimal leakage rates under specified conditions. It features a manual override option requiring minimal force and stroke length for operation flexibility in various scenarios.

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.
