This standard describes electric motor actuators for valves and slide gates in water, wastewater, and reclaimed water utility systems. Electric motor actuators are designed to produce a multiturn rotary motion output to actuate a multiturn valve or gate or to actuate an external gearhead for quarter-turn valves. Electric motor actuators not requiring external gearheads for quarter-turn valves are defined in Sec. 4.4.1.2.
Downloadable versions of current and historical standards are also available.
