Line Blinds

A.J.G Waters Equipment Ltd work with many large manufacturers of specialist equipment such as positive shut-iff line blinds. If your project is in requirement of bespoke line blinds or other types of valves, then please contact us and discuss your requirements.


What is a line blind?

Line blinds provide an additional safety solution designed for positive shut-off of piping, equipment or storage tanks. Isolation valves are not always reliable, which is where positive shut-off line blinds provide a closed, drop-tight, verifiable, and maintainable solution for complete positive shut-off. This positive shut-off feature makes line blinds perfectly attuned for permanent or long-term piping system isolation and shutdown.


Line blinds quickly isolate lines compared to spectacle blinds and are a cost effective solution, reducing labour costs when isolating a system. Line blinds give zero-leakage compared to some isolation valves.
