What is Double regulating valve ?

 Double regulating valve  also known as balancing valves, manual balancing valves, digital lock balancing valves, double-position regulating valves, are used to solve the problem of branch pressure differential balance in pipeline design ball.

Double regulating valve  make it possible to introduce appropriate pressure drops so that each branch of the hydraulic circuit has the required design flow rate. They are equipped with suitable pressure ports which, placed of the ends of a calibrated hole.

Main features of Double regulating valve

Main features and Benifits of NORTECH Static Balancing Valve

  • *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
  • *Numerical indicator of opening rate on the handwheel
  • *Lockable set position
  • * Shut-off function achieved by handwheel
  • * Self-sealing measuring points to protect against leakage
  • *Some reduction in accuracy occurs at partial openings of the valve in accordance with BS 7350

Specifications of Double regulating valve
