When selecting the right industrial valve, buyers often ask:
“Should I use a ball valve or gate valve?”
“Is floating better than trunnion?”
“What makes one valve outlast another in tough environments?”
At Perfect Engineers, we believe in empowering B2B buyers with practical insights. That’s why this page provides a side-by-side comparison of different ball valve types, and real-world case studies to show how correct valve selection leads to measurable improvements in performance, reliability, and ROI.
Choosing the right valve is critical for system performance, safety, and maintenance. If you’re comparing ball valves vs. butterfly valves
When it comes to choosing between a ball valve and a globe valve, the decision largely depends on your application’s flow control needs.
A large petrochemical refinery in Gujarat required a reliable valve solution for its hot thermal oil system. The application involved
A mid-sized dairy facility in Pune producing pasteurized milk and flavored beverages needed a flow control solution that could
The global ball valve market continues to experience robust growth, driven by demand in sectors such as oil & gas, water treatment,

Yes, for viscous or food-grade media. For standard water lines, reduced bore is fine and cheaper.
Use trunnion ball valves for large pipelines and gas lines under pressure.
Not recommended. Always standardize per line unless using adaptors.
Yes, especially for industries needing frequent cleaning, seal replacement, or CIP/SIP operations.
