APEX 1-1/4" Black Plastic High Flow Dual Level Tank Valve

1 1/4 IN Black Plastic High Flow Dual Level Tank Valve
This 1 1/4 inch tank valve is made from polyphenylene sulfide and has a very large flow rate. It utilizes a differential dual weight system that reduces pump wear and saves electricity. This valve is diaphragm activated and has a steel pin that runs inside the pilot center which acts as a self cleaning mechanism which is unique to Apex valves.
