The Sun Hydraulics DNCADJN812 (DNCADJN812) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional valve design with closed transition between positions to minimize oil loss during shifting. This attribute is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, although it allows for reverse flow; optimal performance in reverse configuration is not assured. Engineered for durability and reliability, the DNCADJN812's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring robust performance even under high-pressure conditions. It requires no minimum hydraulic pressure for operation due to its direct actuation mechanism. The valve's construction includes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids which can cause damage. Additionally, the DNCADJN812 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is vital when coils are energized over extended periods as some fluids may degrade at higher temperatures. A variety of coil termination and voltage options are available to suit different operational requirements and environmental conditions. This model also benefits from Sun Hydraulics' innovative magnetic design that enhances solenoid efficiency, yielding a high spool actuating force per watt expended which facilitates reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environments requiring rigorous protection, weatherized coils and kits are available. The DNCADJN812 also features Sun's floating style construction which helps prevent internal part binding due to excessive installation torque or cavity/cartridge machining variations, promoting longevity and consistent performance across various applications.
