ball valves are durable; they can still work perfectly after years of disuse. they do not offer the fine control, but are sometimes used for throttling,which allows for quick shut-off. a v-port ball valve which can be referred to as a type of control valve has the best regulation performance. these valves are suitably used for fluid like fiber, tiny solid particles and slurry medium.
the body of ball valves may be made of metals. such as: forged steel ball valves, stainless steel ball valves, alloy ball valves, bronze ball valves, cast steel ball valves and carbon steel ball valves ect.
stainless steel ball valves.the body can also be made of non-metal materials. ceramic ball valves are erosion-resisting, wear-resisting, cavitation-resisting and antioxidant. besides that, some ball valves materials are special, like, special alloy ball valves, special steel ball valves and hastelloy ball valves ect. transmitting and processing of media that are heavily corrosive, duplex stainless steel ball valves or super stainless steel ball valves are usually selected to mitigate the problems for they can work well in the area with corrosive surroundings..
