Cast Steel Ball Valve
Cast steel ball valves are mainly divided into two types: floating ball valves and fixed ball valves. The characteristic of the floating ball valve is that the ball can produce a certain displacement under the action of medium pressure and is pressed tightly against the sealing surface of the outlet end, thereby ensuring the sealing performance of the outlet end. The ball of the fixed ball valve is fixed and will not be displaced due to medium pressure. It can withstand higher pressure and is suitable for high pressure and large diameter occasions.
