The following data are taken from Mcmaster-Carr Catalog (http://www.mcmaster.com/#globe-valves/=9kmm7e).
Design a similar valve with the following specifications: ·
Use cast steel for the valve body. Design
the body interior to be streamlined for good casting and good flow
characteristics. ·
Have flange ends instead of threaded
connections ·
Use power screw in the stem ·
Ensure that that the valve can be
opened/closed manually Note: You may need to disassemble a valve to better understand its workings. A typical valve used for irrigation or plumbing has many similar components.
