If you turn the adjusting screw clockwise of a spring-loaded, internal pilot, pressure reducing valve, you will __________.

🔍 Key Concepts

• spring-loaded pressure reducing valve construction (adjusting screw, spring, diaphragm, main valve) • relationship between compressing or relaxing a spring and the force it exerts • difference between mechanical spring adjustment and steam pressure in the line

💭 Think About

• Visualize the valve in section: what is the adjusting screw actually pushing on when you turn it in (clockwise)? • When you turn a screw clockwise on a typical spring-loaded device (like a relief valve or regulator), does that usually increase or decrease the compression of the spring? • Which choice talks about something the screw can directly change (mechanical) versus something that changes only indirectly (system pressure)?

✅ Before You Answer

• Focus on what the screw is physically connected to: can it touch steam pressure directly, or only the spring/diaphragm assembly? • Remember that clockwise rotation on an adjusting screw in most valve designs means moving the screw further in, not out—what does that do to the spring length? • Eliminate any answers that confuse spring tension (mechanical force) with line steam pressure (process variable).
