、 The pneumatic butterfly valve is also the most advanced valve in structure at present, its materials are all qualified and verified, and the quality of the pneumatic butterfly valve is also recognized by the national quality inspection unit. The weight is determined after careful consideration, so that the low weight can not only meet the installation requirements, but also be easy to repair or replace in the future. Its service life is verified, and pneumatic butterfly valves used in many industries are durable. Its corrosion resistance is relatively high, and the environment of pneumatic butterfly valves is different. If the environment is relatively harsh, pneumatic butterfly valves are easier to adapt to the environment here than related valves.
