[Fab] went with a simple butterfly valve design, similar to the throttle valve in most gasoline-powered cars. The butterfly vane rotates to vary the flow, turned by a small SG90 servo.

Figure 3. Typical inherent control valve flow characteristics. Figure 4. Installed control valve characteristic for a 0.5 vpdd. The three control valve characteristics are: Linear; Modified parabolic; ...

Choked vapor flow conditions are very common in relief valves and control valves with very high flows, but can also occur in high velocity flare headers at piping transitions. Choked flow is also ...

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.

The design and construction of TX3 Molten Salt valve can withstand temperatures ranging from 260ºC to 600ºC (500 ºF to 1,112 ºF) with standard live-loaded hybrid or Thermiculite ® packing.

Your car's throttle body is the part that connects several engine components, including the air intake and air filter. It also contains a butterfly valve that regulates how much air gets into the ...
