1.Introduction of Ball Valve For Gas Line
Ball valve for gas line refers to long-distance pipelines suitable for natural gas, artificial coal-to-gas, and liquefied gas, and urban gas transmission and distribution network. It is manufactured in accordance with the requirements of GB/T12237-2007, GB/T12224-2005 and related valve standards. Ball valves with fire-proof, anti-static, safe, reliable, and high anti-corrosion performance. It can be specially used for natural gas, coal gas, liquefied gas and other gas and non-corrosive gas pipeline control and flow control.

3. Product Features of Ball Valve For Gas Line
1) Ball valve for gas line anti-static and fireproof device; Ball valve for gas line has a spring electrostatic discharge device to achieve the purpose of removing static electricity. Avoid static sparking and ignite flammable media to ensure system safety.
2) Ball valve for gas line uses PTFE as a seal, which has good lubricity and elasticity, small friction with the ball, and long service life;
3) Ball valve for gas line must ensure that there is no leakage; the leakage volume of natural gas valves is very strict. Generally, buried and more important valves are all welded with valve bodies. In order to ensure the sealing performance of pipeline valves, the sealing pair is required to have excellent corrosion resistance, wear resistance, self-lubricity and elasticity.
4) The selection of Ball valve for gas line materials should be corrosion-resistant and sulfur-resistant materials; because the natural gas transported by the pipeline contains a large amount of hydrogen sulfide before desulfurization (this is a toxic and highly corrosive gas, it reacts with iron to form sulfur Iron can flake off and corrode mechanical equipment). Even if the natural gas is processed by desulfurization and other processes, there is still residual hydrogen sulfide. Therefore, the selection of materials for pipeline valves should be corrosion-resistant and sulfur-resistant materials.
5) The main sealing and wearing parts of Ball valve for gas line pipeline valves such as valve seats and other parts require long life. Generally, the service life of main pipeline valves is more than 30 years.
