How Does a Vertical Check Valve Work?

A vertical check valve is installed directly in-line within a pipe. Water flowing in the correct direction pushes against an internal spring-loaded disc, opening the valve. When flow stops or reverses, the spring immediately closes the valve, preventing water from flowing backward — protecting pumps, meters, and other equipment from pressure loss or contamination.
