Asahi/America”s Series 92 electric actuators are designed for oil and gas applications including pipeline transmission, well-head control, drilling fluids and chemical plants. The NEMA Type 4X, 7 and 9 enclosure is a die-cast aluminum alloy with a thermally bonded powder-coat. The enclosure is bolted together in two sections by eight M8 hex-head cap screws and fitted with an o-ring between the two halves, allowing the actuators to weather harsh and hazardous environments. The internals of the actuator feature a permanently lubricated gear-train and hardened steel spur gears. Two end-of-travel limit switches are mechanically set via adjustable cams for open and close positions. Accessories, such as 4-20 Ma positioners, single and double extra limit switches, heater and thermostat, and two-wire control relays, are available factory installed and calibrated in the actuators.
