APEX 1-3/4" Black Plastic Top Entry Diaphragm Activated Float Valve with Float

1 3/4 IN Black Plastic Top Entry Diaphragm Activated Float Valve with Float
This 1 3/4 inch float valve utilizes a unique way of operation where the pin moves out of the tip of the jet center, pushing any accumulated debris which reduces the valve from blocking. The valve operates at full flow when in the open position reducing wear and tear on the pump while also saving electricity. The valve uses a diaphragm that shuts off the supply of water slowly avoiding any chance of creating water hammer.
