Excessive throttling of the valve had resulted in cavitation-induced erosion damage to areas immediately downstream of the seat. Subsequent investigation indicated that erosion of valve bodies was a generic concern for the other RHR valves used in the same service (FO17A on Unit I and F017A and F017B on Unit 2). flocking examples

"WebAs nouns the difference between valve and throttle. is that valve is a device that controls the flow of a gas or fluid through a pipe while throttle is a valve that regulates the supply of fuel-air mixture to an internal combustion engine and thus controls its speed; a similar valve that controls the air supply to an engine.

What is a Throttling Valve? Definition, Applications, Working ...

WebThe control valves with the best throttling capability have less friction and consequently more leakage. Not all v-notch ball valves have good inherent flow characteristics. For example, one v-notch ball from what I think was a piping valve manufacturer had a flow coefficient of 0% for 0-15% signal. WebIt does this by increasing head loss through the valve (throttling). If the system cannot provide that flow, it behaves as it is fully open, and gives a warning that it cannot deliver the flow. The WaterGEMS FCVs are a subset of all real valves that control flow.
