The Sun Hydraulics DNCADBV72419 (DNCADBV72419) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial for maintaining efficiency in pilot control circuits. The valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min), based on port 3 as the inlet and port 1 as the tank. Designed with a wet armature setup, the DNCADBV72419 ensures that the working fluid surrounds the armature, which could be significant if the coil remains energized over extended periods. This design also helps in managing heat dissipation but requires careful consideration regarding fluid selection to prevent breakdown and varnish formation that could impair valve functionality. Notably, cartridges with EPDM seals are specifically designed for phosphate ester fluids and should not be exposed to petroleum-based substances. The solenoid of this model boasts a unique magnetic design that enhances efficiency and provides robust spool actuating force per watt expended, ensuring reliable valve operation even under demanding conditions. The solenoid tube assembly is fatigue rated for high-pressure applications up to 5000 psi (350 bar). Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has incorporated their floating style construction into this model to reduce risks associated with internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The DNCADBV72419 offers various coil termination and voltage options, some with surge protection, and connector options rated up to IP69K for enhanced environmental resistance. This makes it an adaptable solution suited for diverse hydraulic system applications requiring precise control and reliability.
