Variable Orifice Double Regulating Valve (VODRV) – Ductile Iron

  • These are Y-Pattern globe valves supplied with two pressure test points P84 to provide flow measurement, regulation and isolation
  • The Double Regulating feature allows the valve to be used for isolation and to be reopened to its pre-set position to maintain required flow rate
  • Primarily used in injection or other circuits requiring a double regulating valve for system balancing
  • Accuracy of flow measurement is ±10% at the full open position of the valve
  • Some reduction in accuracy occurs at partial openings of the valve in accordance with BS 7350
