BS1873 Stainless Steel Flange Globe Valve: Precision Flow Control, Engineered for Durability.
Meet our BS1873-compliant Stainless Steel Flange Globe Valve – the robust solution for demanding flow regulation. Crafted from high-grade stainless steel (SS304/SS316), it delivers exceptional corrosion resistance and long service life in harsh environments like chemical processing, oil & gas, power generation, and marine applications. Featuring flanged ends for secure, leak-proof connections and a globe valve design for precise throttling control, this valve ensures reliable performance under high pressure and temperature. Its bolted bonnet facilitates easy maintenance, making it the ideal choice for critical industrial systems requiring safety, efficiency, and adherence to British Standard BS1873 specifications.
Design Features & Construction
Standard: ASTM A351 CF8 (304) / CF8M (316)
