Series P5 PVC Shuttle Flow Switch

Low Cost Flow/No Flow Monitoring, Visual Flow Indication, Broad Chemical Compatibility

The transparent Series P5 Shuttle Flow Switch features corrosion resistant, durable PVC housing for visual confirmation in flow/no flow applications. The switches have preset actuation points from 0.5 to 2.0 GPM for actuation on increasing flow. Switching is SPST normally open at no flow. Choose from 1/2" NPT or 3/4" IPS (for 0.5 GPM) or 1" IPS (for 2.0 GPM) inlet and outlet ports. The shuttle design has only one moving part for long life and minimum maintenance. Remove the one-piece bonnet and shuttle assembly to quickly clean the unit without disturbing the housing or piping. Rugged construction and excellent chemical compatibility simplify flow/no flow detection.
