Ball Valve Used For Flow Control

Rangeability is the useable flow through a valve divided by the minimum useable flow. A ball valve is typically a quarter turn valve with a perforated ball in the middle to control flow. For flow control applications where a ball valve is possible such as filling a tank to a reasonable degree of accuracy a trunnion or v port ball valve design is usually the best choice.

Comprised of a group of quality valve brands from various sectors of the market cnc flow control has an experienced and diversified team dedicated to ensuring the best solutions and superior service.

Ball valve used for flow control. It is open when the ball s hole is in line with the flow and closed when it is pivoted 90 degrees by the valve handle. These valves are known for being durable with excellent shutoff but don t always offer very precise control. Used in many hydrocarbon process applications ball valves are capable of throttling gases and vapors and are especially useful for low flow situations. Let s talk about when it s okay to use a ball valve as a control valve.

Standard ball valves are designed to control flow with a turn of the ball to either be opened or closed. These valves are quick opening and provide a very tight closure on. Ball valves use a metal ball with a hole bored through the center sandwiched between two seats to control flow. Flow control valves are used in a variety of applications such as plumbing mechanical and gas dispensing applications.

A globe valve uses a plug stem that closes against the flow and a ball valve has a gate ball that closes across the flow. For many decades globe valves were considered the industry standard in control valves. The handle lies flat in alignment with the flow when open and is perpendicular to it when closed making for easy visual confirmation of the valve s status. Ball valves for flow control.

Globe valves are good for regulating flow whereas ball valves are better for on off control without pressure drop. Cnc flow control is a premium provider of a wide range of flow control solutions designed to meet the needs of most any application. The ball valve is an inexpensive alternative to other valves. Attempting to control pressure drop or flow rate by actuating the ball less than 90º is really not practical if repeatable accuracy is desired.

A ball valve is a form of quarter turn valve which uses a hollow perforated and pivoting ball to control flow through it. Now with the development of flow tek s characterized v balls a full range of control applications is available with superior flow control. Ball valves have a number of advantages over globe valves better rangeability turndown higher pressure bodies higher capacity 0 leakage and usually lower cost. Standard round ported ball valves have been used and continue to be used for many control applications such as services involving moderate pressure drops.

Globe valves used in the hvac industry typically range from 50 1 for a 6 to only 4 1 for a 1 2.
