The Sun Hydraulics DNCALSV297 (DNCALSV297) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in 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 variability. This model can handle up to 5000 psi (350 bar) with no minimum hydraulic pressure required for operation. Equipped with a wet armature design, the DNCALSV297 allows the working fluid to surround the armature, making it crucial to consider fluid compatibility and temperature exposure \u2014 especially for fluids like water-glycol mixtures that may degrade over time. The valve incorporates Sun's floating style construction to minimize internal binding from installation torque or machining variations. The solenoid's magnetic design offers high efficiency, providing significant spool actuating force per watt expended, ensuring reliable valve shifting. A variety of coil termination and voltage options are available, some offering IP69K ratings for enhanced environmental protection. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. Installation specifics include a cavity T31A configuration with an 8 gpm (30 L/min) capacity and a manual override feature requiring minimal force. The valve exhibits a response time of approximately 50 ms and supports high switching frequencies up to 15,000 cycles per hour. With its robust construction and versatile capabilities, this cartridge valve is suitable for various hydraulic applications requiring precise directional control without compromising on durability or performance stability.

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.
