Key Features & Applications

African Valve supplies high-performance wafer butterfly valves in South Africa for industrial piping systems where reliable shut-off, low operating torque and good sealing are important. These valves are used across water, oil and gas, power, mining, chemical processing and other industrial applications.


The double-offset design allows the disc to move away from the seat as the valve opens. This reduces unnecessary rubbing between the sealing surfaces, helping to limit wear and make the valve easier to operate. The wafer body fits between two pipeline flanges, making it a practical choice where a compact valve arrangement is required.


High-performance wafer butterfly valves are available with different seat, body and disc materials to suit the fluid, pressure and temperature of the application. They can also be operated manually or fitted with pneumatic or electric actuators.
