Technical Advantages Of Gate Valves
Gate Valve uses the gate as the opening and closing part. The gate is driven by the up and down movement of the valve stem to open and close the valve. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. It can be used for a variety of media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc.
This gate valve market is divided into imported ductile iron gate valves, gray cast iron gate valves, and cast steel gate valves according to materials;
According to flange standards, it can be divided into imported American standard gate valves and imported Japanese standard gate valves;
According to the connection method, it can be divided into imported internal thread forged steel gate valves and imported high-temperature and high-pressure power station gate valves (welded gate valves);
It can also be divided according to the valve plate structure, including imported knife-type gate valves and imported pneumatic slurry valves for slurry, coal washing, and mining pulp, and imported flat gate valves for oil drilling, etc.;
The special gate valve market also uses imported elastic seat seal gate valves for water, imported low-temperature gate valves for low-temperature liquid natural gas and low-temperature liquid oxygen, and imported jacketed insulated gate valves with heat preservation and cold preservation for asphalt, thermal oil, etc.
