· 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
· 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
