All - welded ball valves have the following five main characteristics

1. The valve adopts carbon steel seamless steel pipe pressed into shape as an integral welded ball valve.

2. The stem is made of AISI303 stainless steel, and the valve body is made of AISI304 stainless steel, which has been finished and ground, and has excellent sealing performance and corrosion resistance.

3. Carbon reinforced PTFE inclined surface elastic sealing ring is used to seal the surface of the sphere under negative pressure, so that the sealing can reach zero leakage, long service life and other advantages.

4. All-welded ball valve connection: there are welding, thread, flange and other options for users. Transmission mode: handle, turbine, pneumatic, electric and other transmission structure, flexible and portable switch.

5. The valve is compact in structure, light in weight, easy to keep warm and easy to install.
