Vent-Check Valve

A Vent-Check Valve is a type of valve that is classified under the supply class Valves, Nonpowered in the supply group Valves.

A Vent-Check Valve is designed to allow the flow of fluid or gas in one direction while preventing backflow in the opposite direction. It is commonly used in systems where it is necessary to release air or gas from a pipeline or vessel while preventing the entry of fluid or gas from the opposite direction.

The Vent-Check Valve typically consists of a body with an inlet and outlet port, a check valve mechanism, and a vent port. The check valve mechanism allows fluid or gas to flow freely in one direction, while the vent port allows air or gas to be released from the system. When the flow direction is reversed, the check valve mechanism closes to prevent backflow.

Vent-Check Valves are commonly used in various industries, including plumbing, HVAC systems, water treatment plants, and industrial processes. They are essential for maintaining the proper functioning and efficiency of these systems by preventing backflow and ensuring the proper release of air or gas.

Overall, Vent-Check Valves are important components in fluid and gas systems, providing reliable and efficient operation by allowing flow in one direction while preventing backflow.
