Ball Valve

Ball Valve

African Valve is a leading Ball Valve Supplier in Egypt, offering robust and precision-machined valves ideal for reliable shut-off and isolation applications. Our ball valves are designed with a quarter-turn mechanism and a floating or trunnion-mounted ball, ensuring minimal pressure drop and tight sealing under high-pressure and high-temperature conditions. These valves are extensively used across oil and gas, petrochemical, power, and marine industries.

Function & Working

Ball valves function by rotating a spherical ball with a bore through it, allowing or blocking fluid flow when turned 90 degrees. The tight seal between the ball and seats ensures bubble-tight shut-off even in high-pressure or corrosive environments. Their low torque operation makes them suitable for both manual and automated control.
