Pneumatic Butterfly Valve: Actuator Types, Applications and Selection Guide

Learn how pneumatic butterfly valves combine a quarter-turn butterfly valve with a compressed-air actuator for fast and repeatable automated operation. The guide explains double-acting and spring-return actuator options, wafer and lug valve body selection, actuator torque matching, positioner and limit-switch accessories, air-supply requirements, throttling limitations, and key configuration factors for water, HVAC, chemical, food, oil and gas, and industrial automation systems.
