🔍 Key Concepts

• Direct acting air pilot relay operation (how diaphragm movement controls pilot valve and output pressure) • Relationship between pressure at point B and force on the diaphragm/spring assembly • Difference between supply air pressure at G and operating air pressure at F in a relay

💭 Think About

• Trace the mechanical linkage from point B down through the diaphragm, spring, and extension pin to see which component moves first when pressure at B rises • Decide whether an increase in pressure at B tends to open or close the pilot valve/nozzle arrangement at the bottom of the relay • From that valve motion, determine whether output (operating) pressure at F would rise or fall, assuming supply pressure at G is constant

✅ Before You Answer

• Be clear what type of device this is: a direct acting relay (output follows input) vs reverse acting • Verify which side of the diaphragm point B applies pressure to, and which way the diaphragm deflects when that pressure increases • Confirm which port is supply (G) and which is output/operating (F), and how the bottom valve connects or vents these ports when it moves
