we provide different valves under different operating conditions，especially different temperatures. high temperature ball valves, low temperature ball valves are adoptedto work underdifferent operating temperatures. jacket ball valves help to prevent the line fluid’s temperature loss.for high temperature conditions, we can also select high nickel alloy ball valves.under high pressure, our high pressure ball valves are good choices.

according to different types of connection, there are screwed ball valves, flanged ball valves, and welded ball valves. for welded ball valves, they can be divided into butt weld ball valves, socket weld ball valves and fully weld ball valves .a fixed ball valve is suitable for larger and higher pressure. a floating ball valve is different from a trunnion mounted ball valve. in normal operation, with the flow of fluid, the ball will float downstream slightly.

full bore ball valve has an over-sized ball whose hole in the ball has the same size with the pipeline, which resulting in only a small fluid resistance. the pipes can be cleaned easily at the same time.in reduced bore ball valves,fluid flows through the valve whose size is smaller than the valve's pipe size, resulting in reducing the flow.

ball valves in sizes up to 2 inch are generally designed into two or three piece. the ball can be installed in the valve in two different ways, resulting in top entry ball valves and side entry ball valves. for top entry ball valves, the balls can be taken out, repaired and changed easily. the body of ball valves can be a whole and also be modular. they are called integral ball valves and split-body ball valves.
