Ball Valves
Ball valves are quarter-turn valves that use a pivoting, perforated ball to control fluid flow, offering quick and reliable shut-off with minimal pressure drop.
Available in floating and trunnion-mounted designs, ball valves are widely used in industries such as oil and gas, petrochemical, and water treatment for their durability and ease of operation.
Ball valves operate by rotating a hollow, perforated ball 90 degrees to align or misalign the ball's hole with the flow path, enabling efficient on-off control. Floating ball valves, designed to BS5351, are ideal for smaller sizes, while trunnion-mounted valves, per API 6D, support larger, high-pressure applications. Their compact design, low maintenance, and ability to handle various fluids make them a preferred choice in critical industrial systems.
Ball valves are manufactured to meet stringent industry standards, ensuring reliability and compatibility in various systems.
