The Sun Hydraulics DNCADAV4E12V (DNCADAV4E12V) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with closed transition between positions. This design significantly minimizes oil loss during shifting, which is especially beneficial in pilot control circuits. The valve operates efficiently with port 3 as the inlet and port 1 as the tank outlet. While reverse flow through the valve is possible, it is not recommended as performance consistency cannot be guaranteed. This model is fatigue rated for operations up to 5000 psi (350 bar), and functions without any minimum hydraulic pressure requirement, making it highly versatile for various applications. The DNCADAV4E12V employs EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The wet armature design of this valve encompasses the armature in working fluid which aids in heat management from the coil but requires careful consideration of fluid types due to potential breakdown and varnish formation at high temperatures. Additionally, this model offers a range of coil termination and voltage options including designs with surge protection. Its coils are interchangeable within Sun Series 1 solenoid products and can be oriented in either direction upon mounting. Notably, the DNCADAV4E12V showcases Sun's floating style construction which prevents internal binding that can occur due to excessive installation torque or variations in cavity/cartridge machining. This model supports a maximum flow capacity of 8 gpm (30 L/min) and features robust manual override capabilities requiring minimal force. It also boasts rapid response times typical at around 50 ms and maintains operational integrity up to 15,000 switching cycles per hour. With its comprehensive design tailored for high efficiency and reliability, this valve is an excellent choice for demanding directional control applications.
