When selecting the flat gate valve, the following aspects shall be noted:
Operating temperature and pressure range of the valve: ensure that the selected flat gate valve is applicable to the operating temperature and pressure range of the medium. If the material and structure of the flat gate valve cannot bear the working temperature and pressure of the medium, the valve may be damaged or leaked.
Structure of the valve: select the appropriate structure of the flat gate valve according to the application requirements. Different structures have different flow characteristics, operation modes and application scope. For example, the rising stem flat gate valve is applicable to the situation requiring frequent operation or cleaning of the pipeline, while the non-rising stem flat gate valve is applicable to the situation not requiring frequent operation or not easy to clean the pipeline.
Valve material: it is necessary to consider the corrosivity, oxidation, abrasion and other properties of the medium, and select the appropriate valve material. For example, for corrosive media such as strong acid and alkali, the valve material with corrosion resistance shall be selected; For severe working conditions such as high temperature and high pressure, the valve material with good heat resistance and mechanical property shall be selected.
Drive mode of valve: select proper valve drive mode as required. Common valve driving modes include manual, electric and pneumatic, which shall be selected according to actual requirements.
Other parameters of the valve: other parameters of the valve shall be considered, such as flow coefficient, leakage, flow characteristics, etc., as well as the convenience of actual operation and maintenance.
In a word, the selection of suitable flat gate valve needs to consider many aspects, including operating temperature and pressure range, structural form, material, driving mode and other parameters. Comprehensive consideration shall be carried out according to the specific application requirements and working conditions to ensure that the flat gate valve can meet the actual needs and play a good role.
