The Sun Hydraulics DNCALXV236 (DNCALXV236) is a solenoid-operated, 4-way, 2-position cartridge valve designed with a direct-acting, balanced spool directional mechanism. This valve features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a crucial advantage in 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 not recommended due to potential performance issues. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions without requiring minimum hydraulic pressure for operation. This model utilizes EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based substances can damage these seals. The wet armature design allows the working fluid to cool the armature but may lead to varnish formation in certain fluids like water-glycol mixtures if the coil is energized for extended periods. The valve offers various coil termination and voltage options, including configurations with surge protection, enhancing its adaptability across different applications. The solenoid's magnetic design maximizes efficiency by providing high spool actuating force per watt expended, ensuring reliable valve shifts. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube, offering flexibility and ease of maintenance. The coil connector options are rated up to IP69K for superior environmental protection. Additionally, Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve provides robust performance characterized by a typical response time of 50 ms and low leakage rates. It supports high switching frequencies up to 15,000 cycles per hour and includes manual override features for enhanced operational control.
