The Sun Hydraulics DNCATCN524 (DNCATCN524) 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, significantly reducing oil loss during shifting, which is crucial for pilot control circuits. Optimized for a port 3 inlet and port 1 tank configuration, the valve's performance in reverse flow scenarios is not guaranteed and therefore not recommended. It boasts a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar), ensuring durability in high-pressure applications. The valve operates without requiring any minimum hydraulic pressure and incorporates EPDM seals specifically for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model employs a wet armature design where the working fluid surrounds the armature, potentially affecting cartridge function if exposed to prolonged coil-generated heat. A variety of coil termination and voltage options are available, including configurations with surge protection. The solenoid's magnetic design enhances efficiency by delivering high spool actuating force per watt expended, ensuring reliable valve operation. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted bi-directionally on the tube. Additionally, coil connector options provide protection ratings up to IP69K. The DNCATCN524 incorporates Sun's floating style construction to minimize internal part binding due to excessive torque or machining variations during installation. It fits into cavity T-31A and has a capacity of 8 gpm (30 L/min). The valve supports a maximum operating pressure of 5000 psi (350 bar) with typical response times around 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Manual override requires minimal force and stroke effort, while its compact design facilitates easy integration into various hydraulic systems.
