APEX 1-1/4" Black Plastic Diaphragm Activated Top Entry Trough Valve with Float
- Air Gap Provides Backflow Prevention
- UV Stabilized and Corrosion Resistant
- Designed for Compact Top Entry Installation
- Full-flow Operation Until the Trough is Full
This 1 1/4-inch top entry trough valve is designed to control water levels and prevent backflow in medium and large troughs with high demand. It 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. This type of diaphragm valve is essential for preventing contaminants from getting into a water supply. 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. Diaphragm valves regulate where water can enter and exit the valve body. It’s referred to as a diaphragm because a thin film covers the top where water may enter and exit.
In areas where the temperature can be lower than 34°F (1°C) (minimum service temperature) trough valves must be installed as bottom or side entry but NOT top entry.

More Diaphragm Trough Valves
Trough that require backflow prevention should use the top mount valve. Whereas trough with potential for freezing should use the bottom mount valve.
