    Tips: How does a true union ball valve work?

    A true union ball valve is a type of valve that uses a ball with a hole in the middle to control the flow of fluid through a pipe. The ball is usually made of brass or stainless steel, and is seated in a housing made of plastic or other material.

    The valve works by turning the handle attached to the ball. When the handle is turned, the ball rotates, either allowing or blocking the flow of fluid through the valve. When the ball is in the closed position, the hole in the ball is perpendicular to the flow of fluid, preventing it from passing through the valve. When the ball is in the open position, the hole in the ball is aligned with the flow of fluid, allowing it to pass through the valve.

    The true union aspect of the valve refers to its design, which allows for easy removal and replacement of the valve without having to cut the pipe. The valve is made up of three main components: the housing, the ball, and two end connectors. The end connectors are designed to be easily removed from the housing, allowing the valve to be taken apart for maintenance or replacement.

    Overall, a true union ball valve is a reliable and versatile valve that is commonly used in industrial and residential applications to control the flow of water, chemicals, and other fluids.
