GUIDANCE ON VALVE TYPE SELECTIONb.ricardo. Depending on the type of valve, a disc can move linearly inside a valve, or rotate on the stem (as in a butterfly valve), or rotate on a hinge or trunnion (as in a check valve). A ball is a round valve member with one or more paths between ports passing through it. By rotating the ball, flow can be directed between different ports., Ball Valves General: Ball Valves are the most common Valve within the Oil & Gas business. Function: The main function of a Ball Valve is sealing of the flow. A Ball Valve should not be used for throttling (semi open / closed position). This will cause damage the ball due to erosion on the ball it selves. Operation:.

These valves are known for being durable with excellent shutoff, but don’t always offer very precise control. Let’s talk about when it’s okay to use a ball valve as a control valve. Ball valves have a number of advantages over globe valves — better rangeability, turndown, higher-pressure bodies, higher capacity, 0% leakage, and usually, lower cost. Rangeability is the useable flow through a valve, divided by the minimum useable flow. Globe valves used in the HVAC industry typically range from 50:1 for a 6", to only 4:1 for a 1/2".
