A Check Valve is used to control the flow of fluid in a system. It allows the flow of fluid or gas in one direction while preventing backflow in the opposite direction. When the fluid flows in the desired direction, the pressure of the fluid pushes against the valve element, causing it to move away from the valve seat and allowing the flow to pass through. This movement creates an open pathway for the fluid to move freely.Attributes:• Ensures that fluid or gas flows in one direction only• Helps to maintain pressure within a system by preventing pressure loss due to backflowApplications:A Check Valve helps to ensure that fluid flows in one direction only, preventing contamination and proper functioning and safety of the overall delivery system.
