Welding rod extended ball valve with flange structure

1. This valve is made of carbon steel seamless steel pipe pressing forming integral welded ball valve.

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

3. Carbon reinforced PTFE bevel elastic sealing ring is used to seal, and the negative pressure is on the spherical surface, which makes the sealing achieve zero leakage and long service life.

4. The valve connection mode: welding, thread, flange, etc. for users to choose. Transmission mode: handle, turbine, pneumatic, electric transmission structure, flexible switch.

5. The valve has the advantages of compact structure, light weight, easy insulation and installation. This valve is generally installed horizontally.

6. The integrated welded ball valve is developed by absorbing foreign technology and combining with the actual situation in China. It is made in China instead of import and fills in the domestic blank. It is widely used in natural gas, oil, heating, chemical and thermal power pipeline network and other long-distance pipeline fields.
