CI Non-Return Valve is also known as Reflux valve. Water flows from higher pressure to lower. For water distribution in the house water pressure is kept at higher pressure. Sometimes the main pressure is lessened to supply the water to fire fighters. When this happens, the water of house distribution directs to flow towards the main channel. To stop this return and flow, non-return valves are installed. They are installed between the home sewer and the city sewer line connections.
The water of the city sewer line tends to backflow to the home sewer line if the water is filled up to the flowing level. Ci Non-return valves work here to stop the backflow of the sewer water. Non-return valves direct the flow of fluid at one direction only, without the backflow
The valve stops the reversal flow of the fluid. It works on pressure alone without any external help. Mostly non-return valves provide the downstream side of the pump. So, the non-return valve would not limit water hammer in the pipeline. Ranjit Marketing offers premium quality CI non-return (reflux) valves to their clients. We trade in different parts of India.
