The Sun Hydraulics DNCALJV624N (DNCALJV624N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional mechanism. This valve features a closed transition between positions, significantly reducing oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity is rated with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it does not guarantee the same performance and is not recommended. The solenoid tube assembly of this valve is fatigue-rated for service up to 5000 psi (350 bar), and it operates without the need for minimum hydraulic pressure. This model utilizes EPDM seals suitable for phosphate ester fluid systems; exposure to petroleum-based fluids can damage these seals. It employs a wet armature design where working fluid surrounds the armature, potentially affecting performance if the coil remains energized for extended periods. A variety of coil termination and voltage options are available, including those with surge protection. The high-efficiency solenoid design ensures reliable valve shifting by providing high spool actuating force per watt expended. Interchangeable coils with other Sun Series 1 solenoid products allow flexible mounting options, while coil connector options offer protection ratings up to IP69K. Additional weatherized coils and kits are available to enhance environmental protection. The floating style construction minimizes internal part binding due to excessive torque or machining variations in cavity/cartridge installations. The DNCALJV624N has a capacity of 8 gpm (30 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). It features a typical response time of 50 ms and allows a switching frequency of up to 15,000 cycles per hour. The manual override requires a force of 5 lbs/1000 psi at Port 1, with an override stroke of .10 inches (2.5 mm).
