Lug Butterfly Valve | CF8M Disc | PN16

Product Overview

The Tianjin Worlds lug butterfly valve features a ductile iron (GGG40) body with an epoxy coating, a CF8M (AISI 316) stainless steel disc, an SS416 stainless steel stem, and an NBR (nitrile rubber) seat, rated for PN16 (16 bar) service. Its lug‑style body with threaded inserts enables dead‑end service, allowing the valve to be bolted directly to a pipeline flange and withstand full rated pressure from one side – ideal for isolation, maintenance shut‑offs, and future line extensions. The CF8M disc offers excellent resistance to pitting and chloride corrosion, while the hardened SS416 stem provides high strength and wear resistance for reliable torque transmission. The NBR seat ensures bubble‑tight sealing with good oil, fuel, and grease resistance within –20℃ to +100℃, though it is not suited for outdoor UV/ozone exposure or strong acids/bases. Available from DN50 to DN2000, the valve complies with ISO 5211 for direct mounting of actuators, and is widely used in water treatment, oil and gas, fuel handling, and general industrial applications requiring dependable on/off and throttling control with oil resistance.

Tianjin Worlds Valve Co., Ltd. operates under an ISO 9001 certified quality management system and can supply products with CE, UKCA, WRAS, and ACS certifications upon request. We are a direct China-based OEM/ODM manufacturer, producing valves strictly to customer specifications. All materials–body, disc, stem, seat, pressure rating, flange standard, actuation, and coating are fully customizable to meet your specific application requirements. Full documentation (material certificates with mill test reports and pressure test reports) is provided with every order.
