PVC True Union Ball Valves range in sizes from ½” through 4”. PVC True Union Ball Valves are great for high stress environments where the durability of PVC Standard Compact Ball Valves is insufficient and Butterfly Valves are not required. The plastic handle provides ease of this process with a quarter turn. True Union ball valves have double unions that allow for service of the valve whether you are repairing the valve or replacing the valve. The main portion of the valve or carrier is where the handle and ball is located. This can be taken out of line for ease of service without disassembling an entire system. True Union Ball valves come with socket or threaded ends. It is recommended to use PVC glue or thread tape when putting the valves in line. At Drainage Connect, we carry a wide variety of true union ball check valves that help to ensure your system is at the proper pressure and flow rate.
