A gate valve is a valve whose closing member (gate) travels vertically along the centre line of the channel and is typically made up of the following parts: the valve body, the bonnet, the stem gate, the sealing packing, the handwheel/gearbox, and other parts. Typically, studs and nuts are used to secure the valve’s two ends to the pipeline’s flange.
An opening and closing mechanism for a gate valve is a gate. It moves in a direction that is vertical to the direction of the fluid flow. The gate valve cannot be modified or throttled; it can only be used as a shut-off valve. Gate valve sealing comes in two varieties: forced sealing and self-sealing. For self-sealing, the sealing can only be created by applying medium pressure, which presses the sealing surface of the gate against the valve seat on the opposing side to create the sealing. Forced sealing describes a situation where the sealing must be established by using an external force to move the gate plate toward the valve seat when the gate valve is closed.
The flow is unhindered when the valve is opened and the height of the gate is equal to 1:1 of the valve diameter. However, this location cannot be observed when in operation. In a real application, the position is fully expanded until the handwheel cannot be spun, at which point the valve stem’s maximum opening is utilized as a reference. It is advisable to open to the maximum position and turns back 1/2 to 1 turn as a reference to the completely open position of the valve because the handwheel may become stuck during temperature variations. As a result, the valve’s completely open position is determined by the gate’s position (i.e., stroke).
