The Sun Hydraulics DNCALBN224 (DNCALBN224) is a high-efficiency, solenoid-operated, 4-way, 2-position cartridge valve designed for robust hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. It operates effectively with a capacity based on port 3 as the inlet and port 1 as the tank, although it allows for reverse flow under certain conditions. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of this valve is fatigue-rated for demanding applications. The DNCALBN224 does not require minimum hydraulic pressure to function and is direct-actuated. It includes 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 wet armature design of the DNCALBN224 means that the working fluid surrounds the armature which could be relevant when considering coil energization duration and fluid characteristics like water-glycol mixtures that may degrade at high temperatures. With a variety of coil termination and voltage options available, including models with surge protection, this valve offers flexibility in system design. 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 option for coil connectors and enhanced environmental protection options through weatherized coils and kits. The unique magnetic design of its solenoid ensures high efficiency with strong spool actuating force per watt expended, contributing to reliable valve operation even under frequent switching up to 15,000 cycles per hour. The Sun floating style construction minimizes internal parts binding risks due to installation or machining variations. This model also supports manual override capabilities with specific force requirements detailed for effective operation.
