Lesson 12 - Control of Fluid Flow 3
This lesson will consider valve technology, which is used to control fluid flow. It will cover the control functions of on-off, and modulating flow control, together with a description of the various valve types which can achieve these functions. The lesson will conclude with thoughts on the issue of managing valve leakage to avoid cross-stream contamination.
Lesson Sign-off
This lesson concluded our study of flow control by considering valve technology, which is used to control fluid flow. It covered the control functions of on-off, and modulating flow control, together with a description of the various valve types which can achieve these functions. The lesson ended with thoughts on the issue of managing valve leakage to avoid cross-stream contamination.
You should now be able to:
-
Describe the difference between on-off and modulating flow control and give brewing examples.
-
Describe the concept of valve flow rate characteristic and explain why it is important for different aspects of flow control.
-
Discuss various valve types and their principle of operation.
-
Explain the concept of block and bleed and double-seat mixproof valves as a means of managing valve leakage.
A self-assessment lesson now follows, which will allow you to determine the level to which you have attained the above outcomes.
