Choosing the right ball valve isn’t just about size or cost—it’s about ensuring safe, efficient, and long-term fluid control tailored to your process. At Perfect Engineers, we help you make the right selection the first time, by considering all the important technical, operational, and commercial factors that matter in real-world industrial applications.
Whether you’re sourcing valves for water, oil, gas, steam, chemicals, food, pharma, or automation systems, here’s how to select a ball valve that delivers maximum performance and minimum downtime.
Identify the Application
What media will the valve handle?
| Media Type | Example | Best Valve Type |
|---|---|---|
| Water / Air | RO, HVAC, utility | Brass / SS304 / PVC |
| Steam / Thermal Oil | Boilers, power plant piping | SS316 / Metal seated / Fire-safe |
| Chemicals / Acids | Dosing, reactors, ETP | SS316 / Hastelloy / PTFE seats |
| Food & Pharma | Clean-in-place, sterile flow | SS316L / Clamp End / PTFE seats |
| Gas / Fuel / LPG | Pipelines, storage tanks | Fire-safe CS or SS / Trunnion-mounted |
Choose based on your pipeline design:
Match the material to your media and environment:
| Material | Best For |
|---|---|
| SS304/316 | Corrosion resistance, food, pharma, steam |
| WCB / A105 | High-pressure, oil, thermal fluid, steam |
| PVC/CPVC | Budget-friendly, water & light chemicals |
| Brass | Potable water, air, gas |
| Alloy 20 / Hastelloy / Duplex | Aggressive, corrosive chemicals |
Match the valve to your system pressure & temp:
| Rating Type | Options Available |
|---|---|
| Pressure | PN10–PN160 / Class 150–1500 |
| Temperature | -20°C to +450°C (depending on seat) |

Not always. Gas services need tighter sealing (Viton, graphite, or metal seats), while liquid valves can use PTFE or RPTFE.
Floating: Ball is unsupported and seals via pressure.
Trunnion: Ball is fixed; better for large or high-pressure systems.
No. Use full bore if pressure drop is a concern or pigging is required. Otherwise, reduced bore is fine and more compact.
Only if the piping system allows it. Flanged valves are usually preferred in industrial systems due to ease of service.
