The Sun Hydraulics DNCALWV2E12V (DNCALWV2E12V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, significantly reducing oil loss during shifting, which is particularly advantageous in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it may not maintain the same performance level and is not recommended. The solenoid tube assembly of this model is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, this valve operates without requiring minimum hydraulic pressure due to its direct actuation. The DNCALWV2E12V incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. Its wet armature design allows the working fluid to cool the armature but requires careful consideration of fluid breakdown at high temperatures over prolonged coil energization periods. The valve offers various coil termination and voltage options, including those with surge protection for enhanced reliability. This model boasts a unique magnetic design for high-efficiency solenoid operation, providing substantial spool actuating force per watt expended. It supports interchangeable coils from other Sun Series 1 solenoid products and accommodates diverse environmental conditions with coil connector options rated up to IP69K. Additionally, its floating style construction minimizes binding risks due to installation torque or machining variations. The DNCALWV2E12V has a capacity of 8 gpm (30 L/min) and handles a maximum operating pressure of 5000 psi (350 bar). It demonstrates rapid response times typical at 50 ms and maintains minimal leakage rates under specified conditions. With robust construction and versatile application potential, this Sun Hydraulics valve delivers reliable performance across demanding hydraulic systems.
