General Requirements for Pneumatic Sanitary Valves The specifications and categories of the production of pneumatic sanitary valves shall meet the requirements of pipeline design documents. The model of the pneumatic valve should indicate the national standard number requirements. If it is manufactured according to enterprise standards, the relevant description of the model should be indicated. The working pressure of the pneumatic sanitary valve is greater than or equal to the working pressure of the pipeline, and without affecting the price, the working pressure that the valve can withstand should be greater than the actual working pressure of the pipeline; either side of the pneumatic valve should be able to withstand…

7 Points of Pneumatic Butterfly Valve Maintenance
1. The pneumatic butterfly valve should be kept clean during use, and the transmission threads must be regularly lubricated. When a fault is found, it should be stopped immediately to find out the cause and clear the fault. 2. Packing gland bolts should be evenly tightened, and should not be crooked, so as to avoid injury to prevent stem movement or cause leakage. 3. During installation, the valve can be directly installed on the pipeline according to the connection method. Under normal circumstances, it can be installed at any position in the pipeline, but it needs to be easily accessible for maintenance. Note that the medium flow of the shut-off…

Sanitary Valve: Pneumatic Butterfly Valve
The pneumatic butterfly valve consists of a pneumatic actuator and a butterfly valve. It uses a circular disc that rotates with the valve stem as a shutter to achieve the activation action. These valves are mainly used as shut-off valves, and can also be designed to have adjustment or section valve and adjustment functions. At present, butterfly valves are used more and more on low-pressure large and medium-diameter pipes. Pneumatic butterfly valves are classified into stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, and carbon steel pneumatic butterfly valve. The main advantages of the valve are simple structure, small size and light weight,…
