What are the installation precautions for pneumatic butterfly valve?

1, to use the correct method of loading and unloading the valve, to avoid mechanical damage to the valve. When lifting the valve, the sling can not be chained

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

2, in the factory, the valve should be installed at both ends of the simple blind, to avoid water, sand and other impurities in the process of transportation and construction sites into the valve cavity, the seal caused by corrosion and damage

3, in the construction site, the valve is best placed neatly on the sleeper, do not place anywhere, to avoid drainage nozzle, grease injection nozzle, etc. is damaged or broken

4, before installation, the valve must be injected with grease. Through the injection of grease on the one hand to check whether the grease injection channel is smooth on the other hand, the valve seat sealing surface and the back of the cavity filled to avoid impurities into the sealing surface and the back of the cavity, while to a certain extent can weaken the welding high temperature on the valve seat of the damage

5, in the installation of the whole process to keep the valve in the full open position

6, when the welding is completed and do the water pressure test and each time before and after the operation, to make up a certain amount of lubricating grease in a timely manner;

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

8, hard seal butterfly valve valve long-term storage, should be placed in a cool dry place, the valve plate in the open 5 ° - 10 ° state, both ends are blocked and covered, there are packing boxes can be overlapped.

Pneumatic butterfly valve types or more, such as pneumatic clamp butterfly valve, expansion butterfly valve, ventilation butterfly valve and regulating butterfly valves, different butterfly valves are used in different areas, the role played by the role of there is a certain degree of variability. Therefore, for enterprises, in the procurement of butterfly valves, need to consider which type of butterfly valve is more suitable for the working conditions.

In the purchase of pneumatic butterfly valve, is not to focus on the quality of the butterfly valve itself, because the modern butterfly valve are focused on research and development of science and technology, pay attention to the innovation of product technology, so the butterfly valve in the quality of the basic are guaranteed, and the procurement of butterfly valves, the most important thing to consider is the problem of demand. Because different types or different models of butterfly valves, its specific role there are differences, if the enterprise in the procurement of butterfly valves, not for their own needs for a comprehensive analysis, then the procurement of butterfly valves may not be able to meet the needs of the enterprise itself. So in order to ensure that the procurement of butterfly valves suitable for the conditions, buyers in the choice of butterfly valve manufacturers, first of all, to analyze their own needs for what type of butterfly valves, and to demand to determine the type of butterfly valves and models, so as to be able to meet the needs of the working conditions.

Of course, different manufacturers selling pneumatic butterfly valve price also exists a certain variability, for example, Shangzhou Valve created a butterfly valve R & D team, focusing on butterfly valve R & D and design, so that the quality of the butterfly valve is guaranteed, the price is also very fair. Therefore, for buyers in the procurement of butterfly valves, butterfly valves produced by different manufacturers to carry out a comprehensive evaluation and analysis, give priority to the higher evaluation of the pneumatic butterfly valve manufacturers, so that you can buy a satisfactory product.
