The Sun Hydraulics DNCALAN912 (DNCALAN912) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, the DNCALAN912 offers robust performance. However, it is essential to note that while reverse flow is possible through this configuration, optimal performance might not be guaranteed under such conditions. The valve\u2019s solenoid tube assembly is fatigue-rated for demanding 5000 psi (350 bar) service environments, ensuring durability and reliability even under high-pressure operations. This model is particularly suited for systems using phosphate ester fluids thanks to cartridges configured with EPDM seals; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. The DNCALAN912 also features a wet armature design where the working fluid surrounds the armature. This design consideration is vital as prolonged energization of the coil could lead to heat buildup affecting certain fluid types. A variety of coil termination and voltage options are available for this model, providing flexibility in application and installation with additional surge protection configurations if required. Its innovative magnetic design enhances solenoid efficiency allowing for higher spool actuating force per watt expended which facilitates reliable valve shifting. Furthermore, Sun Hydraulics' floating style construction incorporated into the DNCALAN912 minimizes internal parts binding which might occur due to excessive installation torque or machining variations in cavity/cartridge setups. This feature contributes to the overall robustness and longevity of the valve in various hydraulic applications.
