Ball valves operate by using a spherical disc, known as a 'ball', to control the flow of fluid through the valve. They are widely recognized for their ability to provide a tight seal and are ideal for shut-off and control applications. When the valve is open, the ball's hole is in line with the flow, allowing fluids to pass through. When closed, the ball rotates to block the flow. When selecting ball valves, consider specifications such as the size of the valve, the material it is made from (e.g., brass, stainless steel, PVC), and the pressure rating. Additional factors include the type of actuation, whether manual or automated, and the temperature range suitable for the specific application. RFS brand ball valves are designed with innovation and longevity in mind, ensuring reliable service in various industrial environments.
