Description
A butterfly valve uses a rotating disc mounted on a shaft to control flow. When the disc is rotated 90 degrees from closed to open, it presents a thin profile to the flow, minimising obstruction. Butterfly valves are lighter, more compact, and less expensive than gate or ball valves of equivalent size, making them ideal for large diameter pipework (50mm and above).
Autonex is your dedicated source for high-performance butterfly valves in Qatar. Whether your project requires standard concentric wafer butterfly valves for HVAC systems in Doha, or specialized double offset and triple offset butterfly valves for the oil and gas sector, we have you covered. We also supply grooved and flanged options with manual or motorized actuators to suit any industrial specification.
