The Sun Hydraulics DNCADWN814N (DNCADWN814N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. It features a direct-acting, balanced spool with a closed transition between positions to minimize oil loss during shifting. This characteristic is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The valve is designed for direct actuation and does not require a minimum hydraulic pressure to operate, making it versatile across various applications. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of this valve is fatigue rated for high-pressure service environments. The DNCADWN814N can handle a flow capacity of 8 gpm (30 L/min), with port 3 designated as the inlet and port 1 as the tank outlet. While reverse flow through the valve is possible, optimal performance under such conditions isn't guaranteed. Notably, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model incorporates a wet armature design where the working fluid surrounds the armature which might be subject to heat during prolonged coil energization. This factor needs consideration especially when using water-glycol mixtures that may degrade at elevated temperatures. Additionally, the DNCADWN814N offers various coil termination and voltage options including models with surge protection, and its coils are interchangeable with other Sun Series 1 solenoid products allowing for flexible installation orientations. The valve also features Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With its robust design and versatile configuration options, this valve is engineered to provide reliable performance and operational flexibility suited for demanding hydraulic applications.
