The Sun Hydraulics DNCAMWN2E12V (DNCAMWN2E12V) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional capabilities. This valve features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a crucial advantage in pilot control circuits. Designed with port 3 as the inlet and port 1 as the tank, it achieves optimal performance under these conditions, although reverse flow is possible but not recommended. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability in high-pressure applications. Notably, this valve operates without requiring minimum hydraulic pressure due to its direct-actuated design. The DNCAMWN2E12V is compatible with systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based substances should be avoided to prevent seal damage. Utilizing a wet armature design, the surrounding working fluid absorbs heat generated by the coil during extended energization periods. This feature can affect fluid stability over time, especially with water-glycol mixtures that may degrade and impact cartridge function. Offering various coil termination and voltage options\u2014with or without surge protection\u2014this model also boasts a high-efficiency solenoid design that maximizes spool actuating force per watt expended for reliable shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The model provides IP69K-rated coil connector options for enhanced environmental protection and incorporates Sun's floating style construction to minimize internal part binding from installation torque or machining variations. This robust valve has a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), featuring a typical response time of 50 ms and capable of handling up to 15,000 cycles per hour. Its manual override force requirement is minimal at just 5 lbs/1000 psi (33 N/100 bar) at Port 1.
