Metal seated ball valves were introduced to solve problems associated with soft-seated valves whose performance too often degraded in applications that challenged their service limits. The primary advantage of metal over soft seats is their ability to withstand high temperatures and severe service conditions.
Metal-seated ball valves are designed for service temperatures up to and exceeding 1,000 F. Proven in the field, they provide uninterrupted service with the highest shut-off standards for longer time-in-service than soft-seated valves.
I am pleased to announce that we just had our first Million Dollar month. This is another milestone for Flo-Tite and I want to thank all of our loyal distributors and representatives for helping us achieve this important goal. In our continuing efforts to provide the best service in the valve industry Flo-Tite has begun developing video instructions on assembly and disassembly of critical valves and components as a supplement to our printed instructions. This has proven to be invaluable to engineers and maintenance technicians who need that extra “show and tell” to avoid damaging special parts and to preserve the integrity of the valve assembly.
Another Creative Example of Flo-Tite’s Ball Valve Engineering
Being in the business of ball valve engineering, and as a result of our “Ask the Experts” column on our new website, Flo-Tite was contacted by an alert engineer for advice on a problem with an existing application for Heavy Duty Fire Trucks.
The problem was that existing valves mounted with electric actuators closing at 1.5 seconds that are used for controlling water flow to the nozzle could not withstand the pressure versus cycle time, and as a result the upstream seats would rapidly deteriorate.
Long a favorite of process control engineers in Europe, the full-flanged, full-port wafer valve style is finally being recognized in the U.S. as a lighter, lower-torque, space-saving and more cost effective solution.
Shorter in width than a standard flanged ball valve the wafer-style ball valve is ideal for skid systems or any application where space is an issue. With a pocket-less one piece body design, these unique valves eliminate the possibility of body seal leaks. They also add strength to any pipeline.
2011 was another milestone year for Flo-Tite with sales 25% over 2010. We expect our business to grow by another 20% in 2012.

One of the valve industry’s historical problems has been with weld end ball valves in existing process control applications. For years many engineering firms have been searching for valves with extended pipe ends. The issue has been that the rapid heat transfer from the welding process typically damages valve seat materials if not properly handled.
The cost of adding pipe welding to valve ends in many cases exceeds the overall cost of the valves.
