A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it.It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow.It usually turns 90D,120D and 135D. The valve is widely used in petroleum refining, long-distance transportation pipeline, chemical, paper making, pharmaceutical and electric power.
Leflow’s Trunnion ball valve has additional mechanical anchoring of the ball at the top and the bottom, suitable for larger and higher pressure valves.
