The Sun Hydraulics DNCATJN914N (DNCATJN914N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting balanced spool design. This valve is known for its closed transition between positions, which significantly minimizes oil loss during shifting\u2014a critical advantage in pilot control circuits. It is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is engineered to withstand fatigue at pressures up to 5000 psi (350 bar), ensuring robust operation without the need for minimum hydraulic pressure. This valve uses EPDM seals suitable for phosphate ester fluid systems but should not be exposed to petroleum-based fluids as they can cause seal damage. Its wet armature design allows the working fluid to surround and cool the armature; however, prolonged coil energization may lead to fluid breakdown in certain mixtures like water-glycol. The valve offers various coil termination and voltage options, some with surge protection, enhancing its adaptability across applications. The DNCATJN914N\u2019s high-efficiency solenoid design provides substantial spool actuating force per watt expended, promoting reliable valve shifting. Coils are interchangeable within Sun Series 1 products and can be mounted bidirectionally on the tube. The cartridge incorporates Sun's floating style construction to prevent internal binding from excessive installation torque or cavity machining variations. Key specifications include a capacity of 8 gpm (30 L/min), a response time of approximately 50 ms, and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles per hour, with manual override requiring minimal force and stroke length. The model weighs approximately .60 lb (.30 kg) and installs with a torque range of 30\u201335 lbf ft (41\u201347 Nm).
