The forged gate valves supplied by Weldon are primarily designed for on-off services when linear flow and minimum limits of fluid are required. The wedge of the gate valve stops or allows flow through the gate valve and is like the opening or closing of the door. When the gate valve is opened, the closure is completely drawn into the valve leaving a complete opening for the flow. There is almost no pressure drop or flow restriction through the valve.
