REDHAT NEXT GENERATION SOLENOID VALVE GETS PROTECTION AND MORE FROM DUPONT ZENITE LCP
The valve’s solenoid is encapsulated in Zenite and has a coil bobbin molded from the same material inside. An earlier model uses thermoset epoxy for encapsulation. “Our RedHat Next Generation valve using Zenite LCP is ideal for use in hazardous locations, aggressive chemical environments and for indoor and outdoor use where protection is required against splashing water, water seepage, falling or hose-directed water, or severe external condensation,” said Nick Buccheri, vice president of marketing for ASCO. The valves are certified for use in hazardous locations and watertight applications as outlined in Class I, Division 2 of the National Electrical Code, according to ASCO. In addition, they meet all NEMA Types 1 through 4X requirements for water- and dust-tight applications. The encapsulated solenoid withstands ASCO’s stringent thermal shock testing and meets service temperature requirements of, 40 to +200ºC. The RedHat Next Generation line also delivers a sharp reduction in power consumption. Designed to run on either AC or DC power, a RedHat Next Generation solenoid uses only 2 watts of power to deliver the same performance as a typical 17-watt AC solenoid, according to Buccheri. “Their DC performance is up to 500 percent better than that of standard industry units,” he added. RedHat Next Generation solenoids serve in a wide variety of demanding fluid control applications. Among them are air compressors, fire pumps, gas generators, water softeners, metal cutting equipment, welding equipment and water treatment plants. DuPont specialists provided valuable assistance to ASCO engineers during development. They provided support in part design, tooling and processing. The resin grade selected by ASCO, DuPont Zenite 6130, meets this application's needs for resistance to a wide range of aggressive chemicals, a UL94 V-0 flammability classification, excellent stability and cracking resistance in thermal shock testing and excellent performance in the encapsulation injection molding process. It contains 30 percent glass fiber reinforcement. DuPont is a science-based products and services company.
