What is the difference between gate valve and globe valve

The external housing (shell) of gate and globe valves are similar, but the globe valve is designed to serve as a regulating valve, meaning that it can adjust the flow by the percentage of the opening. However, the gate valve is not designed to regulate flow, but to stop the flow. A gate valve should always be either fully open or fully closed. The main difference is in the form of the inner elements and the form of the flow inside the valves. In addition, the gate valve may have a rising or non rising stem while the globe valve is typically a rising stem design. The direction of flow through a gate valve is not important. However a globe valve has a flow direction indicated on the outer shell (body) which indicates the direction of flow from beneath the seat. In a gate valve, the closure element is a plate or disk which travels parallel to the plane of the seat. The gate in a dam is a well known example. In a globe valve, the closure element is usually called a "poppet", and it travels perpendicular to the plane of the seat. There are specific advantages and disadvantages to each type depending on the application. The application for a globe valve is regulating flow. It is not well suited for full stop isolation. The gate valve is an isolation valve and not designed to regulate flow. A gate has a rising disc and is considered positive shut off a Globe offers much more friction losses and is great for throttling ALSO a globe valve is amazing on fire stand pipe systems when one needs to balance the pressure placed on a closed
