Application:

Sight glass and valves are often used together in various marine pipes, industrial and mechanical systems. Sight glasses, typically made of transparent or translucent material like glass , allow operators to visually inspect the flow, level, color, and condition of fluids or gases within a system. Valves, on the other hand, control the flow of these fluids or gases by opening, closing, or partially obstructing the passage.

Combining sight glasses with valves enables operators to not only observe the process but also to control it. For instance, in a pipeline or tank system, a sight glass might provide visibility into the contents, while a valve attached to it allows operators to regulate the flow or shut it off completely as needed. This pairing facilitates both monitoring and control, which are essential aspects of managing fluid or gas systems effectively.
