Which valve can be shifted manually to bypass components?

• A. Bypass Valve
• B. Shutoff Valve
• C. Filter 3 Valve
• D. Bleed Valve

Answer: (C)

A valve that is designed to create an alternate flow path around a component is used to keep the system running while that component is serviced. The Filter 3 Valve is built to be shifted manually to route flow around the third filter. In normal operation, fluid goes through the filter; when you shift this valve, the path bypasses the filter so flow continues even if the filter is out of service or clogged. This capability is what makes it the correct choice. The other valves either stop flow (shutoff), vent air (bleed), or don’t specify a bypass around a particular component, so they don’t serve this purpose.
