Jump to:
+44 (0)1473 277300 Website

Application

Suitable for injection or other circuits requiring a double

regulating valve for system balancing.

Description

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.
