Choosing between an industrial ball valve and a butterfly valve often comes down to pipe size, media, and budget. Although both are manually operated, they handle flow in different ways and are built for very different line sizes. The two valves examined here sit at opposite ends of that decision, and the right pick depends on your specific installation. Understanding their key differences will help you choose.
Quick Verdict
These two valves are built for different jobs. The ball valve is the lower-priced choice when you need a compact manual valve with broad fluid compatibility. The butterfly valve is the higher-priced choice when you need a large manual valve. The $147.91 price gap reflects a major difference in size and intended service. For a small line, the ball valve wins; for a big line, the butterfly valve is the right call.

Where Each Product Wins
- The compact full port ball valve wins on corrosion resistance and fluid versatility. Its 316 stainless steel body and PTFE seals make it suitable for many applications.
- The Pratt Industrial butterfly valve wins on scale. It is designed to serve a much larger pipe, and the valve carries the Pratt Industrial name.
Product Notes
1-1/4\" Full Port Ball Valve
This manual lever ball valve features a 316 stainless steel body and ball with PTFE seals, making it well suited for water, oil, and gas. It has a 1000 WOG rating and a temperature range of -60°F to 450°F, so it can handle demanding conditions within a 1-1/4\" NPT threaded line. Choose it if you need a full-port valve that won't restrict flow in a small bore system. The main limitation is its size: it's only for 1-1/4\" threaded connections, so it won't work in larger flanged or lug-style systems. It's a manual valve, so don't expect actuation.
10\" Pratt Lug Butterfly Valve
This 10-inch lug butterfly valve is a manual valve specified for air and water. The 150# rating indicates its pressure class. It is listed as new open box and described as fully functional after storage. Choose it for large-diameter air or water lines where a lug-style valve is needed. The trade-off is its media scope: the valve is specified for air and water, which is narrower than the ball valve's water, oil, and gas list. And because it's a much larger valve, it requires more space than the compact ball valve.
Final Choice by Use Case
If you need a compact valve that can handle a variety of fluids, the ball valve is the right pick. If you need a large valve for its rated service, the Pratt Industrial butterfly valve is the one to choose. The two products are not interchangeable, so matching the valve to your pipe size and service is essential.
