What is CPVC Butterfly Valve?

The CPVC Butterfly Valve is a quarter-turn rotational speed valve for stopping, regulating and starting flow. In a butterfly valve a disc is mounted on the rotating shaft. The disc stops the line when the butterfly valve is completely closed. The butterfly valve’s disc is at right angles to the flow of gas or liquid when it is fully opened.

The valve can be completely closed or opened by rotating the handle 90 degrees. Large CPVC butterfly valves often have a gearbox attached, which connects the hand wheel to the stem via gears. This makes valve functioning easier, but it comes at the cost of speed.

CPVC butterfly valves are popular due to their dependability and low maintenance needs. Due to less wear, the useful life of the valve can be extended. This minimizes direct operating expenses and the number of hours spent on valve maintenance.
