Jump to:

Application

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 variable orifice double regulating valve, with ANSI version option MHA737.

Features and benefits:

The double regulating feature allows the valve to be used for isolation and to be re-opened to its pre-set position to maintain required flow rate.
Y-Pattern globe valve suitable for flow regulation and isolation.
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.
Supplied with Fig. 631 test points to enable flow measurement.
Valve operation by means of a hand wheel.
