Main features and applications
FBGA mining pneumatic gas butterfly valve is a specialized valve designed specifically for gas characteristics, used in gas pipelines that require quick opening and closing. The inner wall of the gas butterfly valve body is made of a special formula rubber for overall vulcanization, which contains various specialized characteristic components and has the characteristics of flame retardancy, anti-static, corrosion resistance, wear resistance, high rebound, and strong sealing. Effectively prevent corrosion and wear of the valve body caused by gas, and extend the service life of the valve. The characteristics of flame retardancy and anti-static make gas pipelines safer and more reliable. The structural design of bidirectional pressure bearing and bidirectional sealing, as well as the high rebound sealing formula, ensure that the gas valve has desirable sealing performance, truly achieving zero leakage and meeting the requirements for long-term safe operation of coal mines. FBGA pneumatic gas butterfly valve is applied in gas extraction pump stations, gas power stations, coalbed methane transmission pipelines and other projects.
