The Sun Hydraulics DNCADAN (DNCADAN) is a solenoid-operated, 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve designed for efficient hydraulic flow control. It features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's design allows for port 3 to serve as the inlet and port 1 as the tank outlet, although it supports reverse flow with noted performance limitations. With a robust construction, this valve is fatigue rated for up to 5000 psi (350 bar) and does not require minimum hydraulic pressure to operate. It incorporates EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The DNCADAN utilizes a wet armature design where the working fluid surrounds the armature which might affect fluid integrity under prolonged coil energization. This model also boasts high efficiency due to its unique magnetic solenoid design which provides strong spool actuating force per watt expended, ensuring reliable valve operation. The coils are interchangeable with other Sun Series 1 solenoid products and offer various termination and voltage options including options with surge protection. Rated up to IP69K, these configurations enhance durability against environmental elements. Additionally, the DNCADAN uses Sun's floating style construction which helps prevent internal parts binding from excessive installation torque or cavity/cartridge machining variations. This model supports a flow capacity of up to 8 gpm (30 L/min) and has quick response times typically around 50 ms. Its switching frequency can reach up to 15000 cycles per hour with manual override features that require minimal force. This makes the DNCADAN an adaptable solution for diverse hydraulic system requirements where reliability and performance are critical.
