The Sun Hydraulics DNCALAN236 (DNCALAN236) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With its valve capacity optimized with port 3 as the inlet and port 1 as the tank, the DNCALAN236 ensures reliable operation even under reverse flow conditions, although performance consistency in such setups is not guaranteed. Engineered to withstand demanding conditions, the solenoid tube assembly of this model is fatigue rated for service up to 5000 psi (350 bar). The DNCALAN236 operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The valve's wet armature design means that the working fluid surrounds the armature which may be subjected to heat from prolonged coil energization. This design consideration is crucial when using certain fluids like water-glycol mixtures that could degrade under heat. The DNCALAN236 offers a variety of coil termination and voltage options including models with surge protection. Its 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, weatherized coils for enhanced environmental protection, and Sun\u2019s unique floating style construction that reduces internal parts binding due to installation or machining variations. With a maximum operating pressure of 5000 psi and a flow capacity of 8 gpm (30 L/min), this model ensures efficient performance for diverse hydraulic applications while maintaining a rapid response time typical at 50 ms and adherence to stringent leakage standards.
