The Sun Hydraulics DNCADTV814 (DNCADTV814) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional capabilities. This model offers a closed transition between positions, significantly minimizing oil loss during shifts\u2014a feature particularly beneficial in pilot control circuits. The valve operates effectively with port 3 as the inlet and port 1 as the tank, although it allows for reverse flow; performance consistency in reverse orientation is not assured. Engineered for robust performance, the DNCADTV814's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. The valve does not require minimum hydraulic pressure to function due to its direct actuation design. It features EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The DNCADTV814 utilizes a wet armature design where the working fluid surrounds the armature. This setup can lead to fluid degradation if the coil remains energized over extended periods, particularly affecting water-glycol mixtures that may form varnishes detrimental to cartridge functionality. It supports a variety of coil termination and voltage options, including models with surge protection and weatherized coils for enhanced environmental resilience. This model incorporates Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The valve's magnetic design optimizes efficiency by maximizing spool actuating force per watt expended, facilitating reliable shifting. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With an IP69K rating available for certain coil connector options and a variety of configuration choices detailed in the product's CONFIGURATION section, this valve adapts flexibly to diverse operational demands while maintaining high performance standards.
