🔍 Key Concepts

• Pilot (auxiliary) valve operation in a pressure-reducing valve • How a diaphragm moves when outlet pressure acts on it • What actually provides the seating force that keeps a small valve shut when no correcting action is needed

💭 Think About

• Look closely at part "D" in the drawing: what element is directly around or attached to it that could push it into the seat? • Does the diaphragm itself press on the valve, or does it move some other part that then overcomes the normal closing force? • In the normal (steady) condition, what is keeping the auxiliary valve tight on its seat before any pressure change occurs?

✅ Before You Answer

• Trace the mechanical connection from the diaphragm "E" down to the auxiliary valve "D". • Identify which component actually provides the force that pushes "D" against its seat (not just moves a stem). • Verify whether fluid pressure or a mechanical element (like a coil around D) is what holds the valve closed when the system is in balance.
