For many years, the gate valve has been the “go to” valve for isolation, simplicity and availability for process containment. If an application required a block valve, the gate valve was selected 90% of the time. For extreme applications, when the process conditions exceeded the gate valve’s parameters, a ball valve was used. However, we are now seeing that, in certain applications, a triple offset butterfly valve could be a better solution. The triple offset valve offers many advantages like ease of operation, commercial availability with larger sizes even in alloy materials, and a smaller envelope size and weight.
