Translucent Plastic Valve Spring Check Valve

​Spring check valves prevent reverse flow and ensure one flow direction. They have one single inlet and one single outlet that can only be used in the correct orientation for proper functionality. It is called a non-return valve or one-way valve.

​The valve prevents back flow by utilizing a spring or back pressure to close the valve. The valve is often used in applications that have no back flow as even the slightest possibility of back flow may damage the equipment or contaminate the media upstream.
