The Sun Hydraulics DNCADLN712 (DNCADLN712) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures smooth and efficient operation with its closed transition between positions, which minimizes the loss of oil during shifting. This feature is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The DNCADLN712 operates effectively with a valve capacity that considers port 3 as the inlet and port 1 as the tank, although it allows for reverse flow under specific conditions. It boasts a robust solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring durability and reliability even under high-pressure conditions. The valve's direct actuation does not require any minimum hydraulic pressure to operate, making it versatile across various applications. Equipped with EPDM seals, this model is compatible with systems using phosphate ester fluids; however, it should not be exposed to petroleum-based fluids to avoid damage to the seals. The wet armature design of the valve means that the working fluid surrounds the armature which can be a consideration if heat build-up occurs during prolonged energization of the coil. Care should be taken with certain fluids like water-glycol mixtures which may degrade under high temperatures. The DNCADLN712 offers an array of coil termination and voltage options, including models with surge protection. Its magnetic design enhances solenoid efficiency leading to reliable spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options provide ratings up to IP69K for superior environmental protection. This model also features Sun's floating style construction which reduces risks associated with internal parts binding due to installation variances or cavity/cartridge machining inaccuracies. With specifications like a maximum operating pressure of 5000 psi (350 bar), capacity of 8 gpm (30 L/min), and rapid response time typical at 50 ms, this valve is engineered for performance and reliability in demanding applications.
