What are the type of bonnets in the control valves?..

Answer / Rajveer Singh Parmar

Bonnets on control valves serve as covers for the internal mechanisms. Common types include screw bonnets, rising stem bonnets, and yoke bonnets. Screw bonnets have a threaded connection to the actuator, while rising stem bonnets have a stem that rises when the valve opens. Yoke bonnets feature a flat top cover held in place by bolts.
