Valve Selection affects energy consumption in pumping systems. Follow the three steps below to see the energy consumption for various check valves, pump control valves, and shut off valves.
Pump Control Valves are sometimes smaller than the pipe size to lower the initial cost and improve controllability. However, valve size should be selected such that the fluid velocity through the valve doesn’t exceed the recommended maximum for the selected valve types.
Valve headloss can be converted into pump energy cost by the equation:
40-Year Energy Cost = 40 * 1.65 Q ∆h Sg C U / E
