vaccuum ball valve is used to connect or cut off the fluid in a vacuum system.the 3-pcs valve is sealed by a spherical surface,
which allows it to be used in both vaccum state and low pressure state,and to be installed in any position.the valve body and
valve stem are made of stainless steel,and the sealing materials such as valve seat and packing are ptfe,so it is suitable for
media air,water,steam,acid,alkali and so on.
it is suitable for connecting or cutting off the medium flow of gas and liquid with acid or alkali in vacuum system and pressure
system.high vacuum coating and semiconductor industries
