The Sun Hydraulics DNCAMSN214N (DNCAMSN214N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014a crucial aspect for pilot control circuits. The valve 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 standards. The solenoid tube assembly is rated for high fatigue resistance at up to 5000 psi (350 bar), ensuring durability under demanding conditions. This valve operates without requiring a minimum hydraulic pressure and incorporates EPDM seals suitable for phosphate ester fluid systems; however, these seals are incompatible with petroleum-based fluids. The DNCAMSN214N utilizes a wet armature design where the working fluid surrounds the armature, absorbing heat generated by the coil. This feature necessitates caution with specific fluids like water-glycol mixtures that may degrade and form varnishes over time when exposed to heat. The high-efficiency solenoid design provides substantial spool actuating force per watt of energy expended, promoting reliable valve operation. The cartridges are compatible with various coil termination and voltage options, including those with surge protection. Interchangeable coils across Sun Series 1 products offer flexibility in installation direction and connector options rated up to IP69K for enhanced environmental protection. The floating style construction minimizes binding risks from excessive installation torque or machining variations in cavity/cartridge assembly. With a capacity of 8 gpm (30 L/min) and maximum leakage of 10 cu in/min at 3000 psi (160 cc/min at 210 bar), this valve supports up to 15,000 cycles per hour switching frequency while maintaining manual override capabilities with minimal force requirements.
