Butterfly valves are space-saving, quarter-turn valves designed for efficient flow control in systems where space, weight, and cost are critical considerations. With a rotating disc on a central axis, they provide quick operation, low-pressure drop, and reliable modulation.
Their simple, compact construction makes them especially well-suited for large-diameter pipelines across a range of industrial applications.
Butterfly valves are available in concentric, double-eccentric, and triple-eccentric designs, each offering distinct advantages for pressure and sealing requirements.
Concentric models position the disc and stem along the same axis, typically pairing with resilient seats for low-pressure duties. Double-eccentric designs offset the disc and stem axes to reduce seat contact during operation, extending service life and performance under higher pressures. Triple-eccentric valves add a third offset, forming a conical metal-to-metal seal to minimize wear and delivers bubble-tight shutoff in high-pressure, high-temperature, and severe service environments.
Whether in chemical processing, marine service, or water and wastewater systems, butterfly valves are selected for their ability to provide dependable shutoff and modulation with a small footprint.
Their streamlined design supports large flow volumes with minimal energy loss, while the choice of offset configuration allows engineers to match valve performance to specific process demands, ensuring efficiency, reliability, and extended service life in both standard and severe applications.
