🔍 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.

"P" refers to an internal pilot passage sensing evaporator pressure

"P" refers to an internal pilot passage sensing suction line pressure

"Q" refers to an external pilot connection used simultaneously with the internal pilot passage "P"

"A" refers to the adjusting stem used to set the maximum allowable evaporator pressure
