The Sun Hydraulics DNCALCV298 (DNCALCV298) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting which is critical in maintaining the efficiency of pilot control circuits. With a flow capacity based on port 3 as the inlet and port 1 as the tank, it offers reliable operation even though reverse flow is possible but not recommended for optimal performance. Engineered to operate without minimum hydraulic pressure, the DNCALCV298 ensures consistent performance under varying conditions. The solenoid tube assembly of this valve is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. It incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The DNCALCV298 utilizes a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil can lead to fluid degradation at high temperatures. The valve also features a wide range of coil termination and voltage options, enhancing its adaptability across different electrical setups and providing surge protection options. Notably, this model uses Sun's unique magnetic design in its solenoid construction which enhances efficiency and provides a higher actuating force per watt expended. This results in reliable and rapid valve shifting essential for robust system performance. Moreover, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For installation ease and durability, the DNCALCV298 incorporates Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This feature ensures long-term operational reliability and ease of maintenance within hydraulic systems.
