The Sun Hydraulics DNCADLV297 (DNCADLV297) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve operates effectively with port 3 as the inlet and port 1 as the tank, though it supports reverse flow with less guaranteed performance. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of the DNCADLV297 is fatigue rated for demanding applications. It requires no minimum hydraulic pressure for operation, making it versatile across various hydraulic systems. Configurations with EPDM seals are specifically designed for phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. This model incorporates a wet armature design where the working fluid surrounds the armature. This design consideration must be noted as prolonged energization of the coil could lead to fluid breakdown in certain conditions like those involving water-glycol mixtures. The DNCADLV297 offers various coil termination and voltage options, including versions with surge protection and environmental shielding options like IP69K rated connectors. Sun Hydraulics has engineered this valve with a unique magnetic design that enhances solenoid efficiency, providing high spool actuating force per watt expended which ensures reliable valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this model utilizes Sun's floating style construction which helps prevent internal parts binding due to installation torque or machining variations of cavity/cartridge. With a maximum operating capacity of 8 gpm (30 L/min) and quick response time typically around 50 ms, the DNCADLV297 is optimized for high-frequency operations reaching up to 15000 cycles per hour.
