Dn15 Ss 316L Welding Check Valve Nut Connection Type Valve BodyApplications:
Check valve is a valve that 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, beverages, wine, oil, cosmestics, pharmaceutical and chemical industries.Operating principle:
The valve opens when the pressure of the fluid exceeds the pressure to spring, when the two pressures are equalised, the valve closes. A stronger counter-pressure also makes the valve close.Design and features:
