Check valves used to transport liquids, gases or liquids or store in separate pipes. This valve allows the release of content in only one direction. At the moment it does not have an external handle to make them work, they work automatically on the basis of the internal pressure.
They are used in various types of industries. They are manufactured in carbon steel, alloy steel or stainless steel. Mueller Strainer is also manufactured with the help of carbon steel, alloy steel or stainless steel
It is the pressure which opens the valve so choosing the right fit for the pipe is very important. It is used where there is a need for:
– Prevents the reverse flow of liquid or gas contents present in the pipe system.
– Shield other components of the pipe from damage by blocking any flow back.
– to thwart the flow by gravity or pressure variations.
Generally, there follows the check valve type:
Stop C V: Type Valve is designed to cut off the supply of fluids, water, oil or gas regardless of the direction of flow.
Ball C V: Has a round metal ball to cut-off the flow. It is used in pipe systems that carry a gel or liquid contents.
Lift-C V: The valve disc is lifted to facilitate the flow of liquid. The valve closes when the pressure subsides.
In addition to the above-mentioned types there are various other designs of the check valve and each kind of pose different categories, such as a large lift check valve.
