HRSN4D 8850 in/lbs 24V 4/20mA/In/Out NEMA/4/4X/IP67 Electronic/Fail/Safe/Battery/Backup
Product Description
Hayward’s HRS Series Battery Backup electric actuators are designed and produced to provide years of service in demanding industrial environments such as chemical processing, waste and water treatment, power generation, oil & gas, marine, mining, and building services. The integral battery backup system manages battery charge/discharge cycles to provide safe and reliable reserve power in the event of mains power failure. These quarter-turn units drive dampers, ball valves, butterfly valves or inlet guide vanes that require torque ranges from 300 in-lbs up to 177,000 in-lbs. The HR Series housings are designed to meet NEMA 4X environmental demands, with ISO5211 compliant mounting that readily attaches to most valves in the industries served. The HRS2 Series is a compact multi-stage gear train with a lever-less manual override system built in. The HRS3+ Series features an epicyclic transmission system that provides highly efficient multiplication of motor power to produce uniquely compact torque ranges compared to other technologies. A clutch-free manual override system provides full-time override capabilities during powered or un-powered events.Actuator Type
