Pneumatic regulating wafer butterfly valve with stainless steel valve plate, non-rusting

Short Description:

The D671X – 16Q pneumatic wafer soft – seal butterfly valve is composed of a pneumatic actuator and a butterfly valve. A pneumatic butterfly valve is a kind of pneumatic valve that uses a circular butterfly plate rotating with a valve stem as the opening and closing part to achieve opening and closing actions. It is mainly used as a cut – off valve, and can also be designed to have the function of regulation or both cut – off and regulation. At present, butterfly valves are increasingly used on low – pressure large and medium – diameter pipelines.

Classification of pneumatic butterfly valves: stainless steel pneumatic butterfly valves, hard – seal pneumatic butterfly valves, soft – seal pneumatic butterfly valves, carbon steel pneumatic butterfly valves. The main advantages of pneumatic butterfly valves are simple structure, small size, light weight and low cost, and these characteristics are particularly remarkable for pneumatic butterfly valves. Installed in high – altitude dark channels, it is convenient to operate through a two – position five – way solenoid valve, and can also regulate the flow medium. A pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. It is a pneumatic valve that uses a circular butterfly plate rotating with the valve stem as the opening and closing part to achieve opening and closing actions, and is mainly used as a cut – off valve.
