Product Overview
Vacuum butterfly valve is designed and manufactured by welding the middle line butterfly plate and short structure steel plate. It has the advantages of compact structure, light weight, easy installation, small flow resistance, large flow capacity. Avoiding the influence of high temperature expansion and easy operation. There is no connecting rod and bolt in the body, so it works reliably and has long service life. It can
be installed in multiple directions and is not affected by the flow direction of medium.
Structural Characteristics
Manual high vacuum butterfly valve is used to connect or cut off the air flow in vacuum pipeline. The valve has locking function, stable rotation and reliable sealing. Suitable working medium is air and non corrosive gas.
