Which valve is associated with a strainer?

• A. Globe Valve
• B. Check Valve
• C. Ball Valve
• D. PRV

Answer: (D)

Strainers are used to remove debris from the fluid before it reaches more delicate or control components. They’re commonly placed upstream of equipment that governs pressure, because gunk can clog small passages and affect how the device regulates or meters flow. A pressure reducing valve has small internal passages and precise seating surfaces that are particularly sensitive to debris, so a strainer upstream helps protect it and keep the regulation accurate. That protective pairing makes the valve that reduces pressure the one associated with a strainer. Other valves—whether for throttling, isolation, or backflow prevention—don’t inherently require a strainer as part of their normal function, though strainers can be added in dirty systems before any valve if needed.
