Perigo Flushline Throttle Valves are a field proven, economical way to consistently restrict the flow of back flush water. Our valves are all #304 Stainless Steel with grooved ends and feature a welded locking rod which holds the butterfly in a set position while the positioning indicator lets the operator know the exact position of the butterfly. The valve can be opened if needed to clean out any trapped debris.

The valve can be ordered with or without a Sight Tube Assembly. Our sight tubes are made from 1-1/2" U.V. Protected Clear PVC. They install vertically so they are easy to see and drain after each function to help fight algae build up and discoloration.

*Sight Tube Assemblies come with a #304 Stainless Steel Street 90 and Sight Tube with cap.
