The valve stem axis deviates from the center of the disc and the center of the body at the same time, and the rotation axis of the valve seat has a certain angle with the axis of the valve body pipeline, which is called a triple offset butterfly valve.
The scope of application of the triple offset butterfly valve can withstand pressure up to 2500lb , temperature resistance as low as -196℃, up to 700℃, sealing up to 0 leakage, and control ratio as high as 100:1. It means in all kinds of harsh and critical process control pipelines, whether it is an on-off valve or a control valve, as long as the type is properly selected, the butterfly valve can be safely used, and the cost is relatively low.
Product Advantages
‘Cam- action’ and ‘right angled’ conical sealing design ensures that the metal sealing components are never in contact until their final degree of closing – this results in repeatable sealing and a vastly extended valve life.
Metal-to- Metal sealing ensures bubble – tight shut-off, resulting in zero-leakage performance.
Suitability to harsh media – construction of the valve features no elastomers or materials typically affected by corrosion .
Geometric design of sealing components provides friction – free stroking throughout the valve. This extends the valve life and allows a lower – torque actuator to be fitted.
There are no cavities between sealing components, resulting in no clogging, low maintenance and extended valve life.
