Do you know what is the difference between hollow ball and solid ball pneumatic ball valve
Pneumatic ball valve hollow ball and ball valve solid ball is an important part of the entire ball valve, whether it is a general ball valve is still fully welded ball valve, due to the large price of the ball, on the basis of solid developed a hollow ball, two kinds of ball What are the advantages, and the difference? In the planning and manufacturing of pneumatic ball valve, in order to greatly save its planning and processing costs! Ball valves in low pressure pipelines are mostly cast hollow balls.

Ball valves in low pressure pipelines are mostly cast hollow balls.
Hollow ball is mostly casting molding, solid ball is casting! Solid ball must be better than hollow, that is no doubt. Many manufacturers use hollow, only need to make special mention, they will use solid, big factories are necessary to use solid. National standards have never mentioned the hollow ball, hollow ball is some manufacturers in order to save money and manufacturing.
Hollow ball is made by Chinese people in order to reduce their cost and win the bid at a low price. Ball valves include O-ball and V-ball valves, but there is no hollow solid ball. Hollow balls are cheaper than solid balls in cost, especially when stainless steel balls are used, but changes in the working conditions in the pipeline briefly change the center of the hollow balls and fail to achieve the sealing effect.
However, in the process of protecting the pneumatic ball valve, how to properly clean the pneumatic ball valve is also a very important step, so what is the specific cleaning method of each part of the pneumatic ball valve? Below we Wuxi Xinming automatic control valve industry Co., Ltd. for you to clean up the relevant content.
Wuxi Xinming automatic control valve industry Co., Ltd. reminds you that only the pressure before and after the ball valve is removed can the ball valve be disassembled and decomposed. In the process of ball valve decomposition and head equipment, special tools are required to protect seals, especially non-metallic parts, such as O-rings and other parts. Ball valve body equipment bolts must be symmetrical, step by step, evenly tightened. Impurities such as metal fragments, fibers, grease (except for application rules), dust and other impurities and foreign matters such as contamination, adhesion or staying on the surface of parts or entering into cavities are not allowed. What is the specific cleaning method?
The cleaning agent should be compatible with ball valve rubber parts, plastic parts, metal parts and operating media (such as gas). The operating medium is gas, and gasoline (GB484-89) can be used to clean metal parts. Non-metallic parts with water or alcohol. Individual components can be cleaned by decomposition and immersion. The left side of the metal and non-metal still not falling can be used to clean the fine cleaning silk impregnated with cleaning agent (to avoid the partial loss of the fiber) to wipe. When cleaning, remove all grease, grime, glue, dust, etc. When cleaning non-metallic parts, the cleaning agent shall be removed immediately and shall not be soaked for a long time.
The above is the description of the cleaning methods for each component of pneumatic ball valve.
