Fixed orifice vs variable orifice

WebNov 29, 2024 · 4. The Fixed Orifice Double Regulating Valve [FODRV] is also referred to as Commissioning Valve or Commissioning Valve Set. These valves incorporate an orifice or a venturi. The flow coefficient Kvs value of the flow measurement element of these valves is fixed. The pressure differential is referred to as a measurement signal.
