API Gate Valve WCB 600lb 300lb 150lb

The API 600 Gate Valve is mainly used in the petroleum, chemical, food, pharmaceutical, papermaking, water treatment, and other industries to control or adjust the flow of media pipelines. Its main function is to prevent the backflow of media.
The valve body seals the liquid.The front and back covers are the two fulcrums of the transmission device. The valve piece and the valve body are closely matched to form a closed fluid path. A guide mechanism and an adjusting mechanism are installed on the valve body. The back cover is connected with the valve plate to effectively stop the flow of water, increase the pressure loss, and reduce the resistance; there are many kinds of products: double gate, internal seal, external seal (or balance).The API 600 gate valve hoist is located within the valve body and is operated by left and right hand movements or up and down movements.
Handwheels and electric devices can be equipped according to different working conditions.
API 600 gate valve surface materials include cast iron, cast steel, ceramics, composite rubber, PTFE, and so on.
The most serious flaw in a API 600 gate valve is leakage, and excessive leakage not only increases maintenance work but also causes valve body deformation, which has a serious impact on valve life.
Due to medium pressure, the sealing surface of the valve body will have mechanical wear and tear; some have strong wear, and a high temperature of the medium will also lead to valve thermal corrosion. In order to improve the sealing surface material of the API 600 gate valve and its abrasion resistance and impact resistance, many domestic and foreign manufacturers have studied it.
Structural features of API 600 gate valves:
1 The valve body and the flange are connected through an elastic joint so that there is no direct contact between the valve body and the flange, thereby avoiding easy wear, medium erosion, and other problems on the surface of the valve body.
The two ends of the valve stem are made of nodular cast iron, which can improve the rigidity and strength of the valve stem and ensure that no abnormality occurs when the valve stem is opened or closed.
3 The packaging makes use of elastic packing, which is not only small in volume, light in weight, and effective at sealing.
