Q.What Is Check Valve?
TVCCL Check Valve is a dual plate check valve that conforms to API 594.
TVCCL is known as one of the leading manufacturers of Valve in Taiwan since we established.
A check valve, non-return valve (NRV) or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Simply put, a check valve allows flow in one direction and automatically prevents back flow (reverse flow) when fluid in the line reverses direction.
Ceck valve are one of the few self-automated valves that do not require assistance to open and close. Unlike other valves, they continue to work even if the plant facility loses air, electricity, or the human being that might manually cycle them.
Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.
Check valves are found everywhere, including the home. If you have a sump pump in the basement, a check valve is probably in the discharge line of the pump. Outside the home, they are found in virtually every industry where a pump is located.
There are various types of check valves used in a wide variety of applications. Basically, check valve is doing the function of avoiding reverse flow no matter what the type is.
