API gate valves refer to the valves which are made under the regulations set by the American Petroleum Institute. They are usually widely used in petroleum and industrial processing plants, playing an important role at shutting off the flow. And it is true that the featured and core part of them is called the wedge. In order to meet the various specifications, API gate valves are indeed designed and manufactured in multiple sizes, ratings, and materials. No matter what, the main components for these mechanisms are in common. They are the valve gate, valve body, valve bonnet, valve stem and valve seat. van điều khiển khí nén
Firstly, the valve gate is the most effective part. The gate is usually designed in the wedged shape. It seals off fluid flow effectively and enables an appreciated sealing performance. Generally speaking, this device is generally placed against the valve seat.
Refereeing to the valve seat, it means the sealing surface in a API gate valve. From the consideration of reliable performance and long service life, this part is generally made of forged steel. Once it is with some fabrication, it is necessary to repair it immediately, even replace it if necessary.
Secondly, the part called the valve body appears to be also important. It aims to support the valve at installation and maintain the fluid pressure. According to the wide range of the applications, it is necessary and important to choose the proper valve body to withstand certain working extremes.
Besides, the part connected with the valve body is called the valve stem. It is designed to handle the operation of an API gate valves. The turn of the valve stem determines the up and down of the wedge, leading to the control of the flow.
At last, the valve bonnet refers to the flange on the valve body. It is placed to allow for convenient valve maintenance or rebuild. In words, all these basic components cooperate to make contributions to the operation and performance of any API gate valve.
