DN65 to DN300
Variable Orifice Double Regulating Valve (DRV)
Features & Benefits
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
