Ball valve is a efficient valve that control the fluids flow and blockage by rotate the ball.Valves has core advantages such as simple structure, good sealing performance, and convenient operation, and the valve is widely used in industries such as petroleum, chemical engineering, power and water treatment. The working principle of ball valve made in China is to achieve the opening and cutting off of the fluid by rotating the ball with a through-hole 90° under the pressure of the medium. The characteristics of WAITS ball valve is low flow resistance, fast opening and closing, and long service life.

According to the different structural designs, ball valves are mainly divided into the following types:
Floating ball valve : The ball is pressed against the valve seat seal under the pressure of the medium, suitable for small-diameter and medium-pressure working conditions, and the durable ball valve is economical and practical.
Fixed Ball Valve : The ball of WAITS quality ball valve is supported by the upper and lower fixed shafts, suit the high pressure and sealing stable, The classy ball valve is the first choice for long-distance pipelines of petroleum and natural gas. V-ball valve : The ball has a V-Port, which can precisely regulate the flow rate, and is special suitable for high-viscosity media such as slurries and powders.
Double ball valve: The double-ball design in WAITS advanced ball valve make the double sealing safer, and is suitable for high-risk media such as liquefied natural gas (LNG).
Side-entry ball valve: The body can be disassembled from the side, facilitating maintenance, and is suitable for installation environments with limited space.
Top Entry ball valve : The top is detachable, making maintenance convenient, and does not require disassembling the entire valve, suitable for buried or elevated pipelines.
