Flow Controller

Part Number

The Polylok flow controller is ideal for alternating or dividing flows between two separate fields. Easily installed by attaching directly to SCH 40 or SDR 35 pipe, our unique channel split design enables an equal split of the waste stream. Additionally, the valve can be set for equal distribution (factory setting) or all distribution to the right or left.
