Gas ball valve product features
1) Gas ball valve anti-static and fireproof device; Gas ball valve 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) Gas ball valve uses PTFE as a seal, which has good lubricity and elasticity, small friction with the ball, and long service life;
3) Gas ball valve 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 main sealing and wearing parts of Gas ball valve 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.
Gas ball valve produced by MST is suitable for long-distance pipelines of natural gas, artificial coal-to-gas, liquefied gas, and urban gas transmission and distribution network. It adopts a typical floating ball two-piece structure, full-diameter design, stainless steel sphere, and structure. Simple, convenient installation, labor-saving opening and closing operations, easy maintenance, safe, reliable, and high corrosion resistance. It has a wide range of applications and is well received by users.
