8. Research and draw a table to compare four different types of control valves. Your comparison should include mechanical and application differences. 9. Discuss maintenance aspects of a typical industrial control valve. 10. A quick opening ball valve has been installed in a pressure control loop pipeline. The loop is primarily responsible for the safe pressure control of a gas reactor unit. Upon initial testing of the valve it was discovered that the product flow rate changed from 4.67 m³/hr to 7.83 m³/hr when the operator manually changed the valve position from 45% to 85 %. Provide a complete justification whether the installed control valve was suitably chosen? Mention any assumptions made in your answer.
