The Sun Hydraulics DNCAMLN512 (DNCAMLN512) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is particularly beneficial in pilot control circuits due to its closed transition between positions, which significantly minimizes oil loss during shifting. It is designed with port 3 as the inlet and port 1 as the tank, although reverse flow is possible, it is not recommended due to performance concerns. Engineered for robustness, the solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), and the valve requires no minimum hydraulic pressure for operation. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; however, these seals are susceptible to damage from petroleum-based fluids. The valve employs a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil \u2014 a consideration if the coil remains energized for extended periods. The high-efficiency solenoid delivers substantial spool actuating force per watt expended, ensuring reliable valve shifting. Various coil termination and voltage options are available with or without surge protection, and coils can be interchanged with other Sun Series 1 solenoid products. Coil connector options offer ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce potential binding of internal parts due to installation torque or machining variations in cavity/cartridge interfaces. The DNCAMLN512 has a capacity of 8 gpm (30 L/min) and supports a maximum operating pressure of 5000 psi (350 bar). Its typical response time is around 50 ms with a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It can accommodate switching frequencies up to 15,000 cycles per hour and features manual override capabilities requiring specific force and stroke parameters.
