What is the primary purpose of a reach rod as used as a valve remote operator?

Correct Answer: Option D — It allows for the operation of valves that would otherwise be out of reach.

Reach rods are mechanical linkages consisting of rods, universal joints, and bearings designed to transmit torque from a remote handwheel to a valve stem. They are essential for operating valves located in inaccessible areas, such as high overheads or behind bulkheads, ensuring safe and timely system isolation.
