Q:
What would your design or feature "wish list" be for this product?
32 answers
Answers:
1. For valve design we shall consider this application because it will meet with different standards. 2 we shall consider process condition 3. valve type ,floating or trunnion ball valve 4. seat material; metal seat or soft seat 5. if special design of seat ring, stem bushing,extened bonnet etc. 6. Operation type. manual, pneumatic, motor etc

The ability to manage scaling of the ball both in the bore as well as on the sealing faces. Some high scaling applications cause the ball to cement in place and the force to break the scale is beyond the actuator's capability. Secondly scaling of the sealing face of the ball results in seal ride over and subsequent leakage.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of ball valves?

Answers:
Nowadays, all the conventional control valves like globe valves are replaced by ball valves. If at all temperature is not a criteria, ball valves is the best selection to go for ZERO LEAK PROOF valves.
~Prem K, Design Engineer, Chennai, India
Ensure that the valve is correctly applied for the exact process conditions. Ensure temperature is taken into account. In Oil & Gas well applications ensure any sand in the process is taken into account.
~Jeff S, General Manager, Perth, Australia
Get the parameters in selecting ball valves, example get the max temperature, max pressure, flange rating or screwed connection and corrosion guide in selecting the valve materials.
~Engr. Sansin G. Dio D, Sales Engineer, CEBU, Philippines
Not really other than make sure that you specify and accept/use good quality valves from a good manufacturer. You really do get what you pay for otherwise!
~Jay G, Engineer, Endicott, NY
Not used for control application for O type ball valve. And for large size ball valve, you can consider to take triple offset butterfly valve to replace.
~Jerry HE, Project Manager, BEIJING, CHINA
Make sure to review the pressure/temperature rating charts for ball valves. Cold working pressure given in catalog does not give the whole story.
~Process Engineer, Milford, OH
Valve that are not used regularly tend to stick when required to move. These valve should be function tested on a regular basis.
