Hygienic Non Return Valve Butt Weld One Way Flow Check Valve
Working Principle:
1. The flow pressure of both sides of pipe system equals to each other, the valve is closed
2. When flow pressure at bottom side increases, the valve disc is pushes upwards
3. Valve is opened and medium flows through the valve accordingly
4. When flow pressure of both sides return to balance, the spring force pushes the disc back
5. Valve is closed, to stop the medium from flowing back
