The types and application fields of gate valves are introduced

Gate valve is a common fluid control valve, has the advantages of simple structure, good sealing performance, and is widely used in various industries. Gate valves can be divided into many types according to different standards and classification methods. In this article, Lyco Valves will introduce the classification of gate valves and the different application areas.
Classification of gate valves
1. Type by installation position
According to the installation position, the gate valve can be divided into three types: top loading type, hidden loading type and bottom loading type. Top gate valve is mainly connected with the top flange and installed on the top of the pipeline, suitable for small and medium diameter pipelines. The concealed gate valve adopts the axial flange connection mode and is installed inside the pipeline, which has higher requirements for the pipeline. Bottom gate valve adopts bottom flange connection mode, installed at the bottom of the pipe, suitable for large diameter pipe.
2. Sort by structure
According to the structure classification, gate valves can be divided into flat gate valves, parallel gate valves and elastic gate valves. The plate gate valve, with its disc perpendicular to the direction of the fluid, is simple in structure and easy to manufacture and maintain. The disc surface of parallel gate valve is parallel to the direction of fluid, and the disc is translated when the valve is opened, with good sealing performance. The disc of elastic gate valve is made of rubber or plastic material, which has good sealing property but short service life.
3. Sort by material
Gate valves can be divided into cast iron gate valves, steel gate valves and stainless steel gate valves, etc. Gate valves of different materials have different corrosion resistance, high temperature and wear resistance. Select the appropriate material type according to the specific usage scenario.
Application field
1. Petrochemical industry: Gate valves can be used in oil fields, refining, chemical industry and other industrial applications in the petrochemical industry to help control and adjust liquids and gases.
2. Food manufacturing: Gate valves can be used to control and adjust flow and pressure on production lines of condiments, drinks, beer, juice and candy in food manufacturing industry.
3. Tap water and sewage treatment: gate valve can be used for tap water treatment, sewage treatment, seawater desalination and other treatment process flow control and regulation.
4. Industrial wastewater treatment: Gate valves can be used in the process of industrial wastewater treatment, fluid control and regulation in multistage structure, as well as volatile liquid control.
Summary: Gate valves have a wide range of applications and can meet the needs of flow control and regulation in different scenarios. Lyco Valves manufactures and sells all kinds of gate valves to help customers achieve efficient, accurate and stable fluid control.
