Why is the triple eccentric butterfly valve so popular?
The new triple eccentric structure design realizes zero friction, more stable performance, and longer sealing service life. The delicate design ensures that the butterfly valve can be opened and closed flexibly from low to high temperatures, and the sealing performance is excellent, which is fully in line with the sealing standard of zero leakage of the valve under severe working conditions.

What are the main types of gate valves classified according to gate plates?
Generally, it is recommended when the usage conditions or requirements require reliable sealing performance, high pressure, high pressure cutoff (large pressure difference), low pressure cutoff (small pressure difference), low noise, cavitation and vaporization phenomena, high temperature medium, and low temperature (cryogenic). Wedge gate valve. Such as electric power industry, petroleum refining, petrochemical industry, offshore oil, water supply engineering and sewage treatment engineering in urban construction, chemical industry and other fields.

What are the key points and taboos of gate valve installation?
During the installation process of gate valves, butterfly valves and other valves, the quality of the installation will directly affect the normal operation in the future, so you must pay attention to it. Installation taboo 1: Taboo: The main materials, equipment and products used in construction lack technical quality appraisal documents or product certificates that comply with current national or ministerial standards. Consequences: The quality of the project is unqualified, there are hidden dangers of accidents, it cannot be delivered on time, and must be reworked and repaired; resulting in delays in the construction period and increased investment in labor and materials. Measures: The main materials, equipment and products used in water supply, drainage and heating and sanitation projects should have technical quality appraisal documents or product certificates that comply with current standards issued by the state or the ministry; their product names, models, specifications, and national quality standards should be marked. Code number, date of manufacture, manufacturer’s name and location, factory product inspection certificate or code number. Installation taboo 2: Taboo: Failure to carry out necessary quality inspections according to regulations before valve installation. Consequences: During system operation, the valve switches are inflexible, closed tightly and water (steam) leaks...

What is the difference between soft seal gate valve and hard seal gate valve?
Soft seal is the seal between metal and non-metal, and hard seal is the seal between metal and metal. Both soft seal gate valves and hard seal gate valves are made of sealing materials. The hard seal is precision machined from the valve seat material to ensure the accuracy of matching with the valve core (ball), usually stainless steel and copper. Soft seal means that the sealing material embedded on the valve seat is non-metallic material. Since the soft sealing material has a certain elasticity, the processing accuracy requirements will be lower than that of a hard seal.

Why do gate valves require an upper sealing device?
When it is opened, the packing will bear the working pressure. If there is an upper sealing structure, it can prevent the working medium pressure from acting on the sealing packing, extend the life of the sealing packing, and prevent the valve from leaking.
