Ball valve(flanged,wafer)

Fully-welded ball valve is divided into butt weld (BW) and socket weld (SW) types 。
1. the valve seat is designed to be of double lip seal structure to enhance sealing and reduce the operation torque; the valve seat can be made of various materials, suitable for more areas;
2. the valve rod is designed to be of explosion proof structure and bottom mounting type to prevent flying out under pressure; PTFE guide is also used to reduce friction on the valve rod and reduce the operation torque;
3. the valve is designed to be of fireproof and anti-static structure; it can also be customized according to the requirements of the clients or the working conditions.
