Features
03Advantages
- Keeps the suction line full: prevents dry running and the need to re-prime at every start.
- Strainer inlet: stops large solids before they reach the pump.
- Simple design: opens with the flow and closes by itself when the flow stops.
Applications
- Suction lines of centrifugal pumps
- Systems drawing from wells, tanks and basins
- Agricultural irrigation pumps
- Fire water tank suctions
Considerations
- Position the valve below the lowest water level and at a sufficient height above the bottom.
- Clean the strainer at regular intervals; a clogged strainer impairs suction.
