What Is A Split Butterfly Or Containment Valve?Source: ChargePoint Technology Ltd
By Chris Eccles
A Split Butterfly Valve (SBV) or Containment Valve, provides a safe method of transferring product from one container or process vessel to another whilst minimizing the levels of dust emission to the operating environment before, during and after the material transfer.
The SBV concept was originally designed as a Containment device for the contained transfer of Active Pharmaceutical Ingredients (API’s) providing critical operator protection. Many different forms of 'Containment' are adopted within Pharmaceutical and Chemical manufacturing to create a barrier between the operator and the product being handled or processed. You can learn more about Containment, theory, practice and measurement on our Containment Theory page.
Today, the development of SBV technology has increased its suitability for a wider range of industry applications when not only dust control and containment is a concern but where product flow, yield and sterility issues are also prominent.
