Question

Simple gate and globe valves are not better valves.

(a) True

(b) False

I have been asked this question during an internship interview.

The origin of the question is Practical Considerations For Bioreactor Construction topic in chapter Reactor Engineering of Bioprocess Engineering

Answer 1

Correct option is (a) True

Explanation: Common designs such as simple gate and globe valves have a tendency to leak around the valve stem and accumulate broth solids in the closing mechanism. Although used in the fermentation industry, they are unsuitable if a high level of sterility is required.
