What are the installation precautions for pneumatic butterfly valve?

When lifting the valve, the sling should not be directly attached to the valve to avoid causing mechanical damage.

Lifting on the valve stem or actuator, otherwise it will cause the valve stem bending, valve seal failure and gear box damage.

In the factory, valves should be installed at both ends of the simple blind to prevent water, sand, and other impurities from entering the valve cavity during transportation and construction, causing corrosion and damage to the seal.

In the construction site, it is best to place the valve neatly on the sleeper, do not place it anywhere to avoid damaging or breaking the drainage nozzle, grease injection nozzle, etc.

Before installation, the valve must be greased. Grease injection serves two purposes: to check the smoothness of the grease injection channel and to fill the valve seat sealing surface and the back of the cavity to prevent impurities from entering. Additionally, it helps weaken the damage caused by high temperatures during welding on the valve seat.

Keep the valve fully open throughout the installation process.

After welding is completed, conduct a water pressure test and add a certain amount of lubricating grease before and after each operation in a timely manner.

After the water pressure test, the water in the valve cavity should be discharged in time to prevent rusting and icing.

8 inch hard seal butterfly valve should be stored in a cool and dry place for long-term storage. The valve disc should be in the open position at 5°-10°, with both ends blocked and covered. If there are packing boxes, they can be stacked on top of each other.

Pneumatic butterfly valve types include pneumatic clamp butterfly valve, expansion butterfly valve, ventilation butterfly valve, and regulating butterfly valves. Different butterfly valves are used in different areas, and their roles vary. Enterprises need to consider which type of butterfly valve is more suitable for the working conditions when procuring butterfly valves.

When purchasing pneumatic butterfly valves, it is important not to focus solely on the quality of the valve itself. Modern butterfly valves prioritize research and development of technology, ensuring quality. The key consideration in procurement is to analyze the specific needs for different types or models of butterfly valves to ensure they meet the enterprise's requirements. Buyers should first determine their needs and the type of butterfly valves required to meet working conditions when selecting manufacturers.

Of course, different manufacturers selling pneumatic butterfly valve prices also vary. For example, Shangzhou Valve has established a dedicated butterfly valve R&D team, focusing on the research and design of butterfly valves to ensure quality and offer competitive prices. Therefore, when purchasing butterfly valves, buyers should conduct a comprehensive evaluation and analysis of butterfly valves from different manufacturers, giving priority to those with higher ratings, in order to purchase a satisfactory product.
