Q41F40-16 Zhitai Pneumatic lined ball valve

Specifications

  Q41F40-16   Zhitai Pneumatic lined ball valve  

Overview: 
lined ball valve is used as a lining of fluorine plastic, and with new band rod sphere structure, coupled with its unique elastic lip seal seat structure, it has the advantage of ordinary ball, large differential pressure and temperature changes within a high sealing performance and low operating torque. For the use of the switch or adjust the product is suitable for a variety of industrial pipe conveying liquids and gases (including steam), various acids, bases, salts and other corrosive media can well work for. full size valves provide maximum flow, and can be used to scan lines cleaned or quarantined transport pipeline. 
products are widely applicable to a variety of different types of industrial pipe, liquid and gas (including steam gas) conveying severe corrosive media, especially the use of occasions, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia with strong corrosive media.
