In three-port valves, or shuttle valves, internal ridges guide the ball between ports. Restrictive flow regulators work like an automatic variable orifice to control flow by throttling or restricting.

Aligning the hole with the flow path lets fluid pass through; turning the ball 90° stops flow. A ball valve, with its quick shutoff and high-flow capacity, ... Flow-control valves ...

In addition to these two valves, a variety of other Ball Control Valves sizes from 6" to 40" also were delivered to manage water flow in the Riyadh distribution system. About CIRCOR Energy ...

Control valve installed flow and installed gain characteristics comparing a properly sized 3-inch valve and an oversized 6-inch valve in the same system. ... The calculated C V range appears to show a ...

1. Flow-to-open cutaway. Control valves equipped with noise-abatement trim, such as a drilled-hole cage or a tortuous path stack, are typically oriented in the flow-to-open direction.

In this method, attributed to F.C. Yu, the control valve in a pumped application is assigned a minimum pressure drop at maximum design flow rate and maximum 80% control valve open position ...
