Globe valves have bonnetts.

Explanation:
Globe valves typically include a bonnet, which is the component that encloses the stem and packing and provides access for maintenance. The bonnet is bolted or threaded onto the valve body, allowing replacement of the stem packing and servicing the stem-seat interface that governs throttling. Because globe valves are often used for throttling and require precise stem packing adjustments, having a bonnet is standard practice to maintain a tight seal around the stem. Therefore, stating that globe valves have bonnets is accurate in normal valve construction.
