FLOW CHECK VALVE: Generally a flow check valve is installed in your swimming pools circulation system to keep water from flowing backwards when the pump is turned off.
DIVERTER VALVES: Diverter valves usually come in two different types.: 2-way valves or 3-way valves.
- Two way valves control flow to or from one port. The valve can be used to turn the flow completely off, completely on, or anywhere in between by turning the handle through a 90° arc.
- Three way valves have two ends and one center port. Which enable you to close off part of all of the water flow from either end ports, but you cannot shut off the center port. The handle will only rotate 180° on the side opposite the center port.
