Check Valve Selection for Variable-Speed Pumps: Minimum Flow and Disc Stability
Check Valve Selection for Variable-Speed Pumps: Minimum Flow and Disc Stability Quick Summary: Check valve selection for variable-speed pumps must cover the lowest sustained flow through each valve, not only the design flow or pipe size. Ask for the manufacturer’s stable-opening limits, pressure-loss data and closure characteristics for the proposed configuration. Pump minimum flow, valve […]
