Sanitary Check Valve Thread / Thread end
Check valve is for prevents the fluid from flowing back and ensures to flow in only one direction.
It can be used to prevent the flow less from returning avoid pipe hammering.
It is used in the food processing, beverage,wine,oil,cosmetics,pharmaceutical and chemical industrie

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 stronger counter-pressure allows the valve to close.
