Fixed Orifice Double Regulating Valve

Fig. 1209-DF ANSI Flanged Ends for Single Unit Systems Conforms to BS7350
1209-DFM Flanged PN16 or PN25 for Single Unit Systems Conforms to BS7350

Specification:
Single unit Y-pattern globe valves incorporating an integral orifice plate to form a fixed orifice flow measurement unit with regulation and isolation capacity. Valves conform to requirements of BS 7350.

Application:
Primarily used in injection or other circuits requiring a double regulating valve for systems balancing. Accuracy of flow measurement is ±5% at all open positions of the valve in accordance with BS 7350.
