• Primarily used in injection or other circuits requiring a double regulating valve for system balancing.
• Suitable for flow regulation and isolation.
• Supplied with Fig. 631 test points to enable flow measurement.

Ductile iron fixed integral orifice, double regulating valve with ANSI version option MHA739.

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.
• External spray epoxy coated for improved durability.
• Supplied with Fig. 631 test points to enable flow measurement.
