Cast Steel Butterfly Valve

A cast steel butterfly valve is a robust quarter-turn rotary valve engineered for dependable fluid isolation and modulation in heavy-duty industrial pipelines. Fabricated from high-tensile carbon steel (such as ASTM A216 WCB), its cast body provides the structural strength and toughness needed to withstand severe line pressures and mechanical stresses without deformation. The valve controls line media via a disc that rotates 90 degrees on its stem, offering a compact, lightweight footprint compared to traditional gate or globe valves. Available in wafer, lug, or flanged bodies spanning sizes from 2” to 36” (ANSI Class 150–300 LB), they seamlessly integrate with manual levers, heavy-duty gear operators, or automated actuators. Piping project managers and industrial procurement networks can optimize system longevity and secure cost-effective flow isolation by importing certified cast steel butterfly valves directly from leading manufacturers in China via our advanced B2B commercial platform.
