The Sun Hydraulics DNCAMZV71299 (DNCAMZV71299) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This model is particularly notable for its closed transition between positions, which significantly reduces oil loss during shifting\u2014a critical feature for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance degradation. It boasts a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), and it operates without requiring minimum hydraulic pressure. The valve utilizes EPDM seals suitable for phosphate ester fluid systems, while exposure to petroleum-based fluids can damage these seals. This model employs a wet armature design where working fluid surrounds the armature, potentially affecting function if exposed to high temperatures from prolonged coil energization\u2014particularly in water-glycol mixtures. The DNCAMZV71299 offers versatile coil termination and voltage options, including surge protection features. Its unique magnetic design ensures high solenoid efficiency with substantial spool actuating force per watt expended, enhancing reliable valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted bi-directionally on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection, with additional weatherized coils available. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity machining variations. Key specifications include an 8 gpm (30 L/min) capacity, maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles per hour and requires a manual override force of approximately 5 lbs/1000 psi at Port 1.
