The Sun Hydraulics DNCAMTV812N (DNCAMTV812N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Featuring a closed transition between positions, this valve significantly minimizes oil loss during shifting, making it particularly beneficial 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 possible but not recommended due to potential performance issues. It operates effectively without requiring minimum hydraulic pressure and can handle a maximum operating pressure of 5000 psi (350 bar). The solenoid tube assembly is fatigue-rated for high-pressure service. This model incorporates EPDM seals compatible with phosphate ester fluids, but these seals are susceptible to damage from petroleum-based fluids. The wet armature design allows the working fluid to surround the armature, which can be affected by heat generated by the coil over extended periods. This aspect should be considered when using fluids like water-glycol mixtures that may degrade at higher temperatures. A variety of coil termination and voltage options are available, enhancing flexibility in application. The solenoid's efficient magnetic design ensures high spool actuating force per watt expended, promoting reliable valve operation. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Options for coil connectors provide ratings up to IP69K for robust environmental protection. The valve features Sun's floating style construction to reduce risks of binding due to installation torque or machining variations. With a cavity size of T-31A and a series designation of 1, this valve offers a capacity of 8 gpm (30 L/min) and exhibits fast response times typical at around 50 ms. It's built for durability with a switching frequency of up to 15,000 cycles per hour and includes manual override options requiring minimal force for operation adjustments.
