Gas exhaust fully welded ball valve is integral welded ball valve. There is no external leakage. Because the seat is made of carbon fiber reinforced Teflon seal and butterfly spring, it has strong adaptability to pressure and temperature changes. And it will not cause leaks within the pressure and temperature range. The processing of the ball is tracked and detected by an advanced computer detector. So the processing of ball is accurate and high. The gas exhaust fully welded ball valve is widely used in drainage pipe, exhaust pipe, natural gas pipe, etc
