The Sun Hydraulics DNCADWN836 (DNCADWN836) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. It is a direct-acting, balanced spool directional valve designed for efficient control in hydraulic systems. The valve features a closed transition between positions, which significantly reduces the loss of oil during shifting\u2014this characteristic is particularly beneficial in pilot control circuits where maintaining fluid integrity is crucial. The DNCADWN836 operates with a capacity based on port 3 as the inlet and port 1 as the tank. It allows for reverse flow, although this is not recommended as performance consistency cannot be guaranteed under such conditions. The durability of the valve is enhanced by its solenoid tube assembly which is fatigue rated for up to 5000 psi (350 bar). This makes it suitable for rigorous applications without requiring a minimum hydraulic pressure to function. This model incorporates EPDM seals when configured for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the wet armature design of the DNCADWN836 means that the working fluid surrounds the armature which could be subject to heat from prolonged coil energization\u2014a factor that might affect performance if using certain fluids like water-glycol mixtures. Moreover, Sun Hydraulics offers a variety of coil termination and voltage options for this model, enhancing its adaptability to different system requirements and environmental conditions. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Options also include weatherized coils and kits for better environmental protection. Further enhancing its reliability and ease of installation, the DNCADWN836 features Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This model boasts quick response times typically around 50 ms and supports high switching frequencies up to 15000 cycles per hour. With these capabilities and configurations, the DNCADWN836 offers robust performance and versatility in various hydraulic applications.
