The Sun Hydraulics DNCATCV924 (DNCATCV924) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control with closed transition between positions. This feature significantly reduces oil loss during shifting, making it particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), and the valve operates without requiring minimum hydraulic pressure. It incorporates EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based fluids. A wet armature design allows the working fluid to cool the solenoid coil, although users should be cautious of fluid breakdown at high temperatures over time. The DNCATCV924 offers various coil termination and voltage options, including configurations with surge protection. Its high-efficiency magnetic design delivers robust spool actuating force per watt, ensuring reliable valve operation. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. For environmental resilience, coil connector options offer ratings up to IP69K and additional weatherized coils and kits are available. This cartridge features Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It fits into a T-31A cavity and boasts a capacity of 8 gpm (30 L/min) with a maximum operating pressure of 5000 psi (350 bar). The typical response time is around 50 ms, with maximum leakage at specified conditions being 10 in\u00b3/min (160 cc/min). The valve supports high switching frequency up to 15,000 cycles per hour and requires manual override force of about 5 lbs/1000 psi for operation.
