The Sun Hydraulics DNCALJV924N (DNCALJV924N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Featuring a closed transition between positions, this valve minimizes oil loss during shifting, making it particularly advantageous for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is possible but not recommended due to potential performance variances. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. This direct-actuated valve operates without the need for minimum hydraulic pressure. The DNCALJV924N employs EPDM seals suitable for systems utilizing phosphate ester fluids; exposure to petroleum-based substances can damage these seals. Its wet armature design allows working fluid to surround the armature and absorb heat from the coil, which can be a consideration when using fluids that degrade at high temperatures over time. The valve offers various coil termination and voltage options, some with surge protection capabilities. The solenoid's magnetic design provides high efficiency by maximizing spool actuating force per watt consumed, ensuring dependable valve operation. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Coil connector options support ratings up to IP69K for enhanced environmental protection. Constructed with Sun's floating style design, this product minimizes internal part binding due to excessive torque or machining variations. The DNCALJV924N fits into T31A cavities and supports a flow capacity of 8 gpm (30 L/min) with a maximum operating pressure of 5000 psi (350 bar). It has a typical response time of 50 ms and accommodates up to 15,000 cycles per hour switching frequency with minimal leakage rates at specified conditions.
