Working of Gate Valves The working of a gate valve is quite simple. When the gate of the valve is lifted from the flow path, the valve opens and when the entryway again gets back to its position, the door valve closes. This gate movement is achieved by manually turning the hand-wheel. Gate valves work by embeddings a rectangular door or wedge into the way of a streaming liquid. They are worked by a strung stem which interfaces the actuator (by and large a hand wheel or engine) to the stem of the entryway. On the off chance that the valve has a rising stem its position can be seen just by taking a gander at the situation of the stem
