The Sun Hydraulics DNCALCV214 (DNCALCV214) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool for precise control in hydraulic systems. This model features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial aspect in maintaining efficiency particularly in pilot control circuits. The DNCALCV214 operates effectively with port 3 as the inlet and port 1 as the tank, although it allows reverse flow under specific conditions. Constructed to handle demanding applications, the valve is fatigue rated for 5000 psi (350 bar) service and does not require minimum hydraulic pressure for operation. It incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can degrade. The wet armature design of the solenoid ensures that the working fluid surrounds the armature which may be subjected to heat during prolonged energization, potentially affecting fluid integrity over time. Offering flexibility in system design, the DNCALCV214 valve supports a wide range of coil termination and voltage options, including configurations with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include an IP69K rating possibility through specific coil connector options and enhanced environmental protection through available weatherized coils and kits. This model also benefits from Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 8 gpm (30 L/min), and rapid response times typical at around 50 ms, this valve is designed to deliver reliable performance and durability in various hydraulic applications.
