[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.

The Type 567 plastic butterfly valve from GF Piping, Tustin, Calif. (gfpiping.com), works with pressures up to 150 psi.

A butterfly valve is not well suited to throttling and is simply a disk that can be rotated on an axis to control flow (Figure 1). 1. A fully opened butterfly valve.

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.

The plastic valve has an estimated 33% lower impact on climate change during the production phase compared to the metal valve. Throughout the entire lifecycle, the Butterfly Valve 565 requires an ...
