🔍 Key Concepts

• Temperature control valve set point is usually adjusted by changing spring compression on the sensing element. • In a condenser water-regulating valve, the sensing bulb pressure opposes a spring; equilibrium between these forces determines when the valve starts to open. • Rotating an adjusting nut or screw clockwise vs. counterclockwise usually increases or decreases spring compression, changing the temperature set point.

💭 Think About

• Identify which labeled part in the illustration is directly compressing or relaxing the main spring that acts on the bellows or diaphragm connected to the sensing bulb. • Think through how increasing spring compression changes the temperature at which the bulb pressure can overcome the spring and open the valve: does that raise or lower the control temperature? • From common threaded-adjuster behavior, what rotation (clockwise or counterclockwise) would reduce spring compression, and therefore lower the temperature set point?

✅ Before You Answer

• Confirm which label (A or K) is physically in line with and bears on the main spring in the upper housing. • Trace the force path from the sensing bulb (J) through the bellows/diaphragm to the valve plug to see what opposes that force (the spring under the adjusting part). • Before choosing an option, be sure you know which rotation direction would reduce spring tension, as that is the action needed to decrease the temperature set point.
