Application

Suitable for installation where flow needs to be regulated and flow rate measured.

A microset handwheel, fixed orifice operated double regulating valve.

Features and benefits:

The double regulating valve, with its integral fixed orifice design offers an accuracy of ± 5% on all settings, for precise flow regulation and measurement.
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.
Y-Pattern globe valves having characterised throttling disc tending
towards equal percentage performance.
Integral square edged entrance orifice plate and P84 insertion test points fitted.
Double regulating feature allows valve opening to be set with an allen key.
Operation of the valve is by means of the microset handwheel.
