Application

Suitable for injection or other circuits requiring a double

regulating valve for system balancing.

A variable orifice double regulating valve.

Features and 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.
