🔍 Key Concepts

• How an evaporator pressure regulating valve senses pressure (upstream/evaporator side vs downstream/suction line side) • The difference between an internal pilot passage and an external pilot connection in a pilot-operated valve • Identifying the true adjusting stem in the drawing (look carefully at label H vs label A)

💭 Think About

• Follow the small drilled passage marked P and see which main port it communicates with. Is that port connected to the evaporator outlet or the main suction line? • Look at the path from Q into the body (through I and up). Does it appear to be an optional external pilot source, or something that must work at the same time as P? • Compare where A is located with where H is located. Which one is clearly arranged so you could put a wrench or hand tool on it to set the spring compression (and thus the set pressure)?

✅ Before You Answer

• Confirm which side of the valve (port D vs the bottom port) represents the evaporator outlet and which represents the suction line – that will tell you what pressure P is sensing. • Verify whether Q feeds into the same sensing chamber as P, and whether the valve would normally use either internal or external sensing, not both simultaneously. • Make sure you identify the actual adjusting stem (look at label H and its connection to the main spring) before deciding if statement D can be correct.
