This 1 1/4-inch plastic tank valve has a very large flow rate. It utilizes a differential dual weight system that reduces pump wear and saves electricity. You can attach this valve to the bottom or the side of the tank wall. Installing it to the tank wall will ensure there’s limited dead space in the tank itself. This tank 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. This tank valve allows the tank to be fully drained and sanitized. Additionally, the valve can be welded onto the tank for security purposes. Its compact design makes this valve incredibly user-friendly, as well.
