The Sun Hydraulics DNCALBV514 (DNCALBV514) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve operates effectively with a capacity based on port 3 as the inlet and port 1 as the tank, though it allows for reverse flow under specific conditions. Engineered for durability and performance, the DNCALBV514 features a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar). It requires no minimum hydraulic pressure for operation, making it versatile across various applications. The valve is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The DNCALBV514 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is vital when the coil is energized for extended periods since some fluids may degrade under heat and affect valve performance. Furthermore, this model offers a variety of coil termination and voltage options including designs with surge protection. Its magnetic design enhances solenoid efficiency, providing strong spool actuating force per Watt expended which facilitates reliable valve shifting. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and multiple coil connector options that meet up to IP69K standards for environmental protection. The construction uses Sun's floating style to reduce internal parts binding due to installation torque or cavity/cartridge machining variations. This model also supports manual override capabilities and has been designed to handle switching frequencies up to 15000 cycles per hour while maintaining rapid response times typical at around 50 ms.
