A Check Valve, also known as a non-return valve, is designed to allow fluid to flow in only one direction while preventing reverse flow. It typically consists of a valve body with an inlet and an outlet port, a ball, a plug unit, and a sealing mechanism. The primary purpose is to automatically open and close in response to the pressure and flow direction of the fluid passing through it.Attributes:• Hexagonal profile allows for facilitating the secure tightening or loosening of the valve• Helps to prevent damage caused by excessive pressure or sudden changes in pressure Applications:A Check Valve acts as a barrier that allows fluid to flow in only one direction and prevents backflow.
