The R-71600 series low load butterfly valve adopts a metal end face sealing design with a centerline structure. The structure of metal sealed valve seat surrounding the valve plate can reduce the leakage time of the valve seat. This series of butterfly valves has a simple structure, light weight, mature manufacturing process, and convenient maintenance. They are suitable for flow and pressure control in low-pressure conditions At the same time, it can be widely used in industrial sectors such as steel, building materials, petrochemicals, and power plants for fluids at very high temperatures.
