pneumatic PTFE lined wafer butterfly valve

Pneumatic Butterfly Valves are very useful to control highly inflammable liquids like petro-chemicals, Oil, and Gas. It is operated by Pneumatic which allows fast functionality and safe from fire and electric short circuits. So it is an electricity efficient operated valve with the lowest cost.

PFTE-lined butterfly valves offer a durable seal with full chemical resistance. This means that even highly aggressive and corrosive media can be safely routed.

Working principle of pneumatic butterfly valve: The pneumatic butterfly valve uses compressed air as the power source, and drives the valve stem to control the disc-shaped butterfly plate to rotate around the axis. The initial position of the valve is determined according to actual needs.

It is designed to regulate and control the flow of various fluids, including liquids and gases, in pipelines.

Featuring a sturdy construction, this butterfly valve is built with a stainless steel disc. The stainless steel material provides excellent resistance to corrosion, ensuring long-lasting performance even in harsh operating conditions.
