The Sun Hydraulics DNCAMJV912 (DNCAMJV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a closed transition between positions, which minimizes oil loss during shifting\u2014a critical attribute for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly is fatigue-rated for pressures up to 5000 psi (350 bar), ensuring robust performance under demanding conditions. Notably, this valve requires no minimum hydraulic pressure for operation and incorporates EPDM seals suitable for systems using phosphate ester fluids, though exposure to petroleum-based fluids can damage these seals. The DNCAMJV912 employs a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil\u2014a consideration when using fluids prone to breakdown at high temperatures like water-glycol mixtures. This design enhances the efficiency of the solenoid, providing high spool actuating force per watt expended for reliable valve shifting. The product offers versatile coil termination and voltage options with or without surge protection, and its coils are interchangeable with other Sun Series 1 solenoid products. Featuring Sun\u2019s floating style construction, this valve minimizes internal part binding risks due to excessive installation torque or machining variations. It fits into a T-31A cavity with an 8 gpm (30 L/min) capacity and supports a maximum operating pressure of 5000 psi (350 bar). With a typical response time of 50 ms and switching frequency up to 15,000 cycles per hour, it provides efficient operation in various applications. Additional specifications include manual override capabilities and compatibility with Viton seal kits for both cartridge and coil components.
