Product Description

 Pneumatic butterfly valves use compressed air as a power source to drive the valve stem and drive the valve plate to rotate 0-90 degrees inside the valve body, thereby achieving full open and full closed operation control of the butterfly valve. Each valve undergoes a pressure test and is only shipped after passing the zero leakage test.The valve body material is ductile iron, and the sealing ring material can be selected from EPDM and PTFE. The valve plate can be selected from ductile iron and 304 stainless steel.
