A screwed end non-return valve, also known as a check valve or one-way valve, is a type of valve that allows fluid to flow in only one direction. It is commonly used in plumbing and industrial applications to prevent backflow and ensure the flow of fluids in the desired direction.
The "screwed end" part of the name refers to the threaded connections on the valve's ends, which allow it to be screwed onto other pipes or fittings. This type of valve is typically screwed onto a pipe, and the flow direction is indicated by an arrow on the valve body.
