PVC ball valves are also often used in aquariums and other aquatic environments to regulate water flow and prevent backflow.

    PVC ball valve applications

    Tips: How much pressure can a PVC ball valve hold?

    The maximum pressure that a PVC ball valve can hold depends on several factors, including the size of the valve, the material of construction, and the specific application in which it is being used. Generally, PVC ball valves are designed to withstand pressures up to 150 psi (pounds per square inch) at room temperature.

    However, it is important to note that the maximum pressure rating of a PVC ball valve can vary depending on the temperature and the type of fluid being conveyed through the valve. Higher temperatures and more corrosive fluids can reduce the maximum pressure rating of the valve, so it is important to consult the manufacturer's specifications and guidelines to ensure that the valve is suitable for your specific application.

    Additionally, it is always recommended to follow proper installation and maintenance procedures to ensure the longevity and reliability of the valve.
