Check Valve Manufacturers

Avlok is a leading check valve manufacturers and suppliers. There will be no compromise in terms of quality because our check valve sellers only sell certified valves for better customer satisfaction. The Check valves are activated by the line fluid pressure and closed by gravity. The back pressure of lime fluid also facilitates sealing. We manufacture & export a whole line of Check valves including Brass, Stainless Steel, Relief & Non-return Valves that cater to varied industrial requirements hold the following.

What is the purpose of a check valve?

Check valves are mounted generally in pipelines to avoid back flow. A check valve essentially is a one way valve, wherein flow is allowed in one direction, but if the flow reverses, the valve automatically closes and safeguards the piping, other valves, pumps etc.
