G Type Fully Welded Ball Valve

G-type fully welded ball valves are integral welded ball valves made of carbon steel pipe press molding. It is mainly used for gas output pipeline, large heating equipment output pipeline, pipeline and each circuit opening and closing, fluid pipeline, exhaust gas discharge pipeline, gas supply pipeline, heat treatment pipeline, industrial gas and heat pipeline and so on.

Fire safe design: According to API **7/BS***5 specification. In the event of a fire at the valve site, the sealing ring made of secondary sealing non-metallic material is decomposed or destroyed at high temperature, and the primary metal seal can be quickly attached to the ball to seal. The unique two-stage sealing seat structure design ensures the reliability of valve seat fire protection.

Anti-static design: The electrostatic extraction device of spring and small ball is used to form an electrostatic channel between the ball and the valve body through the valve stem, so that the static electricity caused by the friction between the ball and the sealing ring is led to the earth through the valve body, which can prevent fire or explosion and other hazards caused by electrostatic sparks.
