A PPH Single Union Ball Check Valve is a specialized check valve combining a ball check mechanism with a single union connection (versus the dual unions in a True Union design).
It shares the same core function as True Union ball check valves - permitting unidirectional flow while preventing backflow. However, its single-union construction offers a more budget-friendly alternative, letting customers choose based on their specific needs.
