A microset handwheel operated, fixed orifice double regulating valve.
Application
Suitable for installation where flow needs to be regulated and flow rate measured.
Description
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.
