Welding ball valve structure and 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. Connection method of the valve: welding, thread and flange are available for users to choose. 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. This valve is normally installed horizontally.

6. Integrated welding ball valve from foreign advanced technology, combined with the actual situation in China developed, to replace the import of domestic.

Widely used in natural gas, oil, heating, chemical and thermoelectric pipe network and other long - distance pipeline field.
