ASTM A536 65-45-12 Butterfly Valve

An ASTM A536 65-45-12 butterfly valve is a versatile and economical quarter-turn rotary valve cast from high-grade ductile iron to deliver dependable fluid control across municipal and industrial utility networks. The specific 65-45-12 metallurgical designation guarantees a minimum tensile strength of 65,000 psi, a yield strength of 45,000 psi, and a 12% minimum elongation capacity, providing excellent structural resilience and thermal shock resistance compared to standard gray cast iron. Featuring a concentric disc that seals against a compressible elastomer liner (such as EPDM or NBR), it achieves absolute bubble-tight shutoff while isolating the outer valve body from direct contact with the process fluid. Civil infrastructure contractors and industrial utility builders can optimize pipeline efficiency and achieve outstanding project cost-effectiveness by importing certified ASTM A536 65-45-12 butterfly valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
