Hastelloy C276/B3 Ball Valve
High Performance • Durable • Leak Proof
Hastelloy C276/B3 Ball Valve Manufacturer in Africa for corrosion-resistant flow control.
Technical Specifications
Key Features & Applications
Large-bore and high-pressure chemical systems can produce seat loads that make a floating ball valve difficult to operate. Supporting the ball on trunnions reduces this movement and allows the seats to move toward the ball. African Valve is a leading Hastelloy C276/B3 Ball Valve Manufacturer in Africa, supplying South Africa, Nigeria, Egypt, Angola and major African and export projects.

Pressure and Cavity Control
When the valve is closed, pressure may become trapped in the body cavity. A pressure-relief arrangement allows excess cavity pressure to discharge to the upstream or downstream side according to the seat design.Double-block-and-bleed capability should be confirmed from the exact valve configuration. It should not be assumed solely from the trunnion-mounted construction.
Applications
C276 trunnion valves are used in corrosive chemical transfer, offshore injection, chlorine-processing systems and pollution-control pipelines. B3 versions suit selected reducing-acid service where the process chemistry is controlled.
Manufacturing and Inspection
Large nickel-alloy valves require controlled casting or forging, machining and welding. PMI, NDT, dimensional inspection, shell testing, seat testing, cavity-relief checks and actuator functional testing may be included.
Large-Bore Project Supply
African Valve supplies C276 and B3 trunnion-mounted ball valves for chemical and pipeline projects across Africa. RFQ data should include chemistry, size, pressure, temperature, isolation arrangement, seat design, end connections, actuation and inspection scope.
