The types of electric ball valves are: floating ball valve, fixed ball valve, rail ball valve, V-type ball valve, three-way ball valve, stainless steel ball valve, forged steel ball valve, ash discharge ball valve, sulfur resistant ball valve, three-way ball valve, pneumatic ball valve, electric ball valve, ferrule ball valve, welded ball valve, flange ball valve, thread port ball valve.

Floating ball: the ball of the ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end. The floating ball valve has simple structure and good sealing performance, but the load of working medium borne by the ball is transferred to the outlet seal ring. Therefore, it is necessary to consider whether the seal ring material can withstand the working load of the ball medium. When it is impacted by high pressure, the ball may shift. This structure is generally used for medium and low pressure ball valves.
