Primarily designed to meet the stringent requirements and safety levels of the oil & gas industry, this high performance butterfly valve is available in a range of sizes, from 2 inches to 80 inches (DN 50-2000). This makes them ideally suited for a host of applications, including firewater, hydrocarbons, cargo handling, bilge and ballasts and utilities, just to name a few.
Series - 150 | PN6-PN25
Manufactured to ASME 150 features a soft polymer seat. Customers can specify PTFE, RTFE or UHMWPE seats, depending on their application and the performance characteristics required.
The new valve is available in a choice of body materials , carbon steel for general applications, 316 stainless steel and duplex stainless steel for applications requiring superior corrosion resistance.
