A fixed integral orifice, double regulating valve.
Application
Suitable for injection or other circuits requiring a double
regulating valve for system balancing.
Description
A fixed integral orifice, double regulating valve.
Features and benefits:
- Single unit Y-pattern globe valves incorporating an integral orifice plate to form a fixed orifice flow measurement unit with regulation and isolation capacity.
- 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.
- Accuracy of flow measurement is ±5% at all open positions of the valve in accordance with BS 7350: 1990.
- Primarily used in injection or other circuits requiring a double regulating valve for system balancing.
