The Sun Hydraulics DNCALAV212N (DNCALAV212N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. The valve features a direct-acting, balanced spool with closed transition between positions, minimizing oil loss during shifting\u2014a critical factor in pilot control circuits. It is engineered to handle a capacity of 8 gpm/30 L/min with a maximum operating pressure of 5000 psi/350 bar. This valve is notable for its direct actuation which does not require minimum hydraulic pressure to operate. The DNCALAV212N is equipped with EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based substances should be avoided as it can damage the seals. The design incorporates a wet armature setup where the working fluid surrounds the armature; this could lead to fluid breakdown if the coil remains energized for extended periods, especially with water-glycol mixtures. This model offers flexibility in terms of coil termination and voltage options, including configurations with or without surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For enhanced durability and environmental protection, various weatherized coils and kits are also available. Additional features include an IP69K rating possibility for coil connectors depending on the specific configuration chosen, ensuring high resistance to dust and water ingress under severe conditions. The unique magnetic design of the solenoid ensures efficient operation by generating high spool actuating force per Watt expended, which facilitates reliable valve shifting. Sun Hydraulics' DNCALAV212N also benefits from a floating style construction that reduces risks associated with internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This robust construction along with its advanced technical specifications make it an ideal choice for demanding hydraulic applications requiring precise flow control and reliability.
