The EZ-FLO CBV-100 is a 1" Coupler with Ball Valve. Connectors are available for mainline sizes ranging from 3/4″ to 4″ with socket x socket connections for gluing into PVC pipe. They are manufactured from Schedule 40 PVC with 1/4″ 304 stainless steel barbed tubing connections. They are used to connect the EZ-FLO system to the irrigation flow line before or after the valve with the 1/4″ flexible tubing provided with every EZ-FLO system. Ball Valve Connectors provide the ability to adjust the differential pressure between the inlet and outlet connections to the irrigation system and ensure injection across a wide range of flow rates.
