Watts Dual Check Valve
check valve
- A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.
- Limits the flow of gas to one direction only. Use a check valve between the bubbler and generator to prevent unwanted pressure build up in the generator, and a safety against a low level bubbler. A check valve, such as used on torches, is recommended.
- A valve that closes to prevent backward flow of liquid
- A mechanical device in a pipe that permits the flow of water or air in one direction only.
