The standard check valve has a wide variety of applications, impacting many different industries – from hospitals and pharmaceuticals to power and refining. How exactly do these valves work?
Flow Sensitivity is a Key Element
All check values are designed for flow sensitivity. These tools depend greatly on the successful opening and closing of the line fluid. Keep in mind that a check value’s main job is to prevent reverse flow within a standard piping system. When this type of backwards flow emerges within a system, the check valves are usually the first areas examined for damage and/or defects.
Basic Construction, Efficient Performance
There really is not much to a check valve when it comes to the design and assembly. The key components of a valve usually consist of a cover, disc, seat and full body. In some cases, there are high-quality valves – such as alloy 20 check valves – that come with a more enhanced design.
Such enhancements on these types of premium valves may include hinge pins, elastomers, springs and disc arms. However, the basic function of a check valve is consistent across the board regardless of its design or enhanced structure.
Where is the Weight?
Unlike most valves that need at least some sort of dampened device or weighted element, check valves are designed for self-sustenance. As mentioned above, the overall structure and build of a check valve is very simplistic in nature. It is not very complex at all and comes in a variety of sizes and materials to properly fit whatever application or project you may need. From plastic and carbon steel to a wide range of alloys and iron, there is likely at least one type of check valve that can work well and boost the airflow efficiency of almost every piping system regardless of setting.
