The Sun Hydraulics DNCALZN836 (DNCALZN836) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, which minimizes oil loss during shifting\u2014an essential attribute for pilot control circuits. With a valve capacity based on port 3 as the inlet and port 1 as the tank, reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This direct-actuated valve does not require minimum hydraulic pressure for operation and utilizes EPDM seals suitable for systems with phosphate ester fluids\u2014caution is necessary as exposure to petroleum-based fluids can damage these seals. The DNCALZN836 employs a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil, potentially affecting function if energized for extended periods. High-efficiency solenoid design ensures reliable valve shifting with significant spool actuating force per watt expended. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction, offering versatility in application. Coil connector options provide ratings up to IP69K for enhanced environmental protection, with additional weatherized coils available. Incorporating Sun's floating style construction minimizes internal part binding due to excessive installation torque or machining variations. The valve supports a capacity of 8 gpm (30 L/min) and operates efficiently within its maximum pressure rating of 5000 psi (350 bar). It features a typical response time of 50 ms and can handle switching frequencies up to 15000 cycles per hour. The manual override requires a force of 5 lbs at 1000 psi (33 N at 100 bar), with an override stroke of .10 in (2.5 mm).
