Shell structure: the valve body of the fixed ball valve can be designed into three types, namely, cast structure, forged structure and all welded structure, according to the user's needs and actual working conditions. The ball valve with all welded structure is mainly suitable for underground use.

Next in installation, it is necessary to install the pneumatic switch ball valve on the pipeline. It is suggested by Yossi Fluid that the ball valve should be installed on the upper end. If it is a valve with an actuator, it should be installed horizontally. One small detail that we should pay more attention to is that the bolts on the flange should be tightened symmetrically and evenly. In addition, according to the pipeline design requirements, the sealing gasket should be installed between the valve flange and the pipeline flange to connect the pneumatic pipeline.
