Which component has a function that mirrors the make-up valve in basic configuration and operation?

• A. Unloading valve
• B. Gland seal regulating station
• C. Bypass valve
• D. Stop-check valve

Answer: (A)

Valves that control how much fluid enters or bypasses a system do so to keep pressure and level within set limits. A makeup valve and an unloading valve share that same control idea: they regulate flow by creating or removing a path for fluid to reach the system and thus maintain the desired condition. The unloading valve mirrors the makeup valve because, in basic setup and operation, it serves to manage flow to the system by bypassing excess discharge when the set condition is met, effectively preventing unnecessary work and keeping pressure steady in the same way a makeup valve keeps the system supplied when losses occur. The other components have different primary roles: gland seal regulating station handles gland leakage control, bypass valve diverts flow around a component, and stop-check valve prevents backflow.
