Frequently Asked Questions.
A ball valve is a quarter-turn valve that uses a hollow, perforated ball to control the flow of fluids or gases. When the ball’s hole aligns with the flow path, the valve is open; when rotated 90 degrees, it shuts off flow. It is widely used for on/off control in various industries.
Ball valves are preferred in applications requiring quick on/off control, tight sealing, and durability under high pressure and temperature. They are ideal for handling gases, liquids, and slurries, and are commonly used in flow isolation, process control, and emergency shut-off systems. Typical uses include oil and gas pipelines, chemical and petrochemical processing, water treatment plants, HVAC systems, and power generation. Ball valves are also favoured in industries like food & beverage, pharmaceuticals, and marine systems for their reliability, low maintenance, and ease of operation.
Ball valves offer fast operation, tight sealing, durability under high pressure and temperature, and low flow resistance. They are also easy to operate and maintain, making them reliable for demanding applications.
When selecting a ball valve, consider factors such as the type of fluid, pressure and temperature ratings, flow requirements, valve material, and connection type. Referencing industry standards and manufacturer specifications ensures the valve meets performance and safety requirements.
