AWWA Check Valve
Valvesonly has been the greatest Awwa Check Valve Manufacturer in USA. Awwa valves operate the flow and pressure of fluids, gases, and slurries within a structure. They have a long life and trouble-free performance. They are majorly preferred by customers because of their low cost and lightweight. They are considered very reliable, and effective and do not ask for regular maintenance.
The Check Valve is also known as one way valve, which allows the flow of fluids to move in one direction only. The check Valve also helps to prevent backflow in the system. It may cause problems if the flow is contaminated and therefore contaminates the media upstream. The application of check valves is the protection of upstream equipment, preventing media contamination and it prevents from drainage.
Some characteristics of check valves are moving parts of the valve are low inactivity, the distance through which the moving elements must travel is minimal, mechanical assistance of closure motion of moving elements like spring, tight seal leakage, and low-pressure loss.
