Product Introduction

A pneumatic butterfly valve is a type of butterfly valve that uses compressed air or gas to operate the valve. It uses a wafer-style body design and operates by moving a disc or plate inside the valve to regulate or control the flow of fluids. The pneumatic actuator is attached to the valve and is responsible for opening and closing the valve. When the actuator receives a signal, it uses compressed air or gas to move the valve disc to the desired position. The pneumatic wafer butterfly valve is commonly used in industries where there is a need for rapid and precise fluid control, such as in chemical processing, water treatment, and food and beverage production.

The pneumatic butterfly valve equipped with the pneumatic actuator is relatively fast, and does not require workers to do it by themselves. It saves human resources and time to a large extent.
