Sanitary check valve, also known as "non-return valve", is designed for use in process piping installations to prevent reverse flow. VCN series is a spring check valve with different connection ends. A check valve opens when the pressure below the valve plug exceeds the pressure above the valve plug and the spring force. The valve close when pressure equalization has been achieved.
Operating Principle
The Valve opens when the pressure of the fluid exceeds the pressure exerted by the pump spring.When the two pressures are equalised, the valve closes. A stringer counter-pressure allows the valve to close.
