    PVC ball valves are commonly used in a variety of industries, including water treatment, irrigation, chemical processing, and HVAC systems. They are particularly useful for controlling the flow of fluids or gases in pipelines and can be found in both commercial and residential applications. PVC ball valves are also often used in aquariums and other aquatic environments to regulate water flow and prevent backflow.

    Tips: What is a true union ball valve?

    A true union ball valve is a type of valve that is commonly used in piping systems to control the flow of fluids. It gets its name from its design, which incorporates a union fitting that allows the valve to be easily installed and removed from the piping system without having to cut or disassemble the entire system.

    The ball valve itself consists of a hollow ball with a hole through the center that can be rotated 90 degrees to either allow or prevent the flow of fluid through the valve. When the ball is in the closed position, the hole in the ball is perpendicular to the direction of flow, blocking the passage of fluid. When the ball is rotated 90 degrees, the hole aligns with the direction of flow, allowing fluid to pass through the valve.

    The true union design allows for the valve to be easily taken apart for maintenance or repair, without having to cut or disassemble the entire piping system. This is achieved by incorporating two union fittings, one on each side of the valve body, which can be easily disconnected and reconnected using threaded nuts. This feature makes the true union ball valve a popular choice for applications where frequent maintenance or repair is required.
