American standard flange gate valve is suitable for ANSI Class 150 ~ 2500lb, working temperature - 40 ~ 500 ℃, used to cut off or connect the medium in the pipeline. American standard flange gate valve can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media by selecting different materials. There are manual, bevel gear transmission and electric, etc.
Flow. The gate has two sealing surfaces. The two sealing surfaces of the common mode gate valve form wedge, and the wedge angle varies with the valve parameters. Wedge gate valve can be made into a whole, called rigid gate; it can also be made into a small amount of deformation of the gate, in order to improve its process, to make up for the deviation of sealing surface angle in the process of processing. This kind of gate is called elastic gate.
Product features:
1. According to the requirements of advanced standards at home and abroad, the sealing is reliable, the performance is excellent and the appearance is beautiful.
2. The gate and valve seat are wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant and have long service life.
3. Wedge type elastic gate structure is adopted, and rolling bearing is set in medium and large diameter, so it is easy to open and close.
4. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.
5. Various piping flange standards and flange sealing face types can be used to meet various engineering needs and user requirements.
6. The material of valve body is complete. The packing and gasket are selected according to the actual working condition or user's requirements. It can be applied to various pressure, temperature and medium conditions.
