Valves DOE-HDBK-1018/2-93 TYPES OF VALVES Plug Valves A plug valve is a rotational motion valve used to stop or start fluid flow. The name is derivedfrom the shape of the disk, which resembles a plug. A plug valve is shown in Figure 13. Thesimplest form of a plug valve is the petcock.YPES OF VALVES DOE-HDBK-1018/2-93 Valves On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respectto percent of opening. This means that flow rate does not change evenly with stem travel.Also, a partially open gate disk tends to vibrate from the fluid flow.
