Fire Gear Wafer Butterfly Valve

The Fire Gear Wafer Butterfly Valve from Waits Valve is the core product of my fire protection series and has obtained ISO 9001 certification from DNV, Bureau Veritas, ABS, and Lloyds. This series of butterfly valves adopts high-quality B148 C9500 valve body and plate, as well as Monel K500 valve stem. If you have any other requirements, feel free to contact us!

The butterfly plate is located at the center of the pipeline, and a rod passing through the butterfly plate is connected to the actuator outside the valve. Rotating actuators can make the butterfly plate parallel or perpendicular to the direction of fluid flow. Unlike ball valves, butterfly valves are always located within the fluid flow range, so regardless of the valve position, pressure drop will occur in the fluid.
