What type of valve is the solenoid operated butterfly valve?

Explanation:
A solenoid operated butterfly valve is a fast-acting, electric-controlled valve that uses a rotating disk (butterfly) to regulate bleed air. In a gas turbine, bleed air valves control air taken from compressor stages to systems like engine starting, anti-ice, or environmental control. The later, high‑pressure bleed path requires quick, precise modulation and reliable shutoff, which a solenoid-driven butterfly valve provides with simple, compact actuation and good sealing. That combination is typically used for the high-stage bleed air path, which is why the valve described is associated with the high-stage bleed (often the last bleed stage in the compressor).
