электрические пневматические дроссельные заслонки

China electric pneumatic butterfly valves are two types of valves that are often used for controlling flow in pipelines. Electric butterfly valves use an electric actuator to control the valve’s position, while pneumatic butterfly valves use compressed air to actuate the valve.
Будущее stainless steel pneumatic butterfly valve looks promising, as these types of valves continue to be widely used in various industries such as water treatment, ОВК, и химическая обработка.
