Valve Flow Co-efficient (Cv)
One of the primary costs after the initial capital outlay is running costs, especially in a pump station. A valve’s Cv determines the pressure drop between the inlet and outlet ports of the valve. The lower the pressure drop the higher the Cv, which in turn results in lower power consumption of the pump. We at Hydrocore have modelled a standard globe valve (SGV) to determine its Cv.
The calculator works out the power penalty cost of a Hydrocore Isolating Valve versus a SGV. As is evident, the cost savings using a Hydrocore Isolating Valve versus a SGV are astronomical even within the first couple of years. Assuming that the price of electricity is not going to go down in the future, those cost savings will only increase.
