The proper selection of the non-return check valves for pumping systems is very important and some elements are to be considered for selection.
The type of application, the pressure drop, water hammer and the energy consumption and acquisition costs
For smaller pumping systems these elements are less significant, however in bigger systems these elements can have an important impact on the total energy consumption.
At Castflow Valves we can assist with the technical support in order to select most recommendable valves and materials.
Castflow has developed new improved rubber lined check valves for applications with corrosive fluids. Our retainerless rubber lined check valves guarantees a drop tight valve without weak areas that normal rubber lined valves present.
The complete 1 piece rubber lined valve does not contain glued union of rubber and guarantees a uniform rubber thickness all over the metal surface in contact with the fluid.
In addition, our rubber lined ball check valves are exclusive on wastewater market. For applications with fluid containing sludge, solids, etc. we can offer a rubber lined ball check valve that allows the passage of these solids and resist the corrosion or abrasion of the fluid.
Stainless steel or superduplex ball check valves are another option for corrosive applications.
