The SS316 SS304 API vacuum butterfly valve can be used to control the opening, closing or intermediate position of the valve by means of a manual index switch to achieve the purpose of turning the air flow in the vacuum line on or off. Suitable for high vacuum lines in air and non-corrosive gases.
1. It is designed and manufactured by adopting the new structure of medium-line disc and short-structure steel plate welding. It is compact in structure, light in weight, easy to install, small in flow resistance, large in circulation, avoiding the influence of high temperature expansion, and easy to operate.
2. No connecting rods, bolts, etc., reliable operation and long service life. Can be installed in multiple stations, independent of media flow.
