The Sun Hydraulics DNCAMWN814 (DNCAMWN814) 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, significantly reducing oil loss during shifting\u2014a critical advantage in pilot control circuits. It is optimized for operation with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance degradation. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve requires no minimum hydraulic pressure for operation and incorporates EPDM seals suitable for systems using phosphate ester fluids. However, these seals are vulnerable to damage from petroleum-based fluids, greases, and lubricants. The valve's wet armature design allows the working fluid to cool the armature but may lead to varnish formation in water-glycol mixtures if exposed to prolonged coil heat. Offering various coil termination and voltage options with or without surge protection, this valve boasts a unique magnetic design that ensures high efficiency and reliable shifting with minimal power consumption. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options provide protection up to IP69K standards, with additional weatherized coils available for enhanced environmental resistance. The DNCAMWN814 features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It has a capacity of 8 gpm (30 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The typical response time is 50 ms with a maximum leakage of 10 in\u00b3/min at 110 SUS (3000 psi). It supports a switching frequency of up to 15,000 cycles per hour and includes manual override capabilities for added operational flexibility.
