The pneumatic rubber-lined butterfly valve imported from Doldr, Germany is a simple structure valve, which is mainly composed of valve body, valve disc, valve stem and sealing ring and other components. It uses a pneumatic actuator as the driving device, and realizes the opening and closing of the valve by controlling the opening and closing of the air supply. This kind of valve has the advantages of simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, and can also have good flow regulation function and closing sealing characteristics at the same time.
The imported pneumatic rubber-lined butterfly valve has a small flow resistance when fully opened. When the opening is between approx. 15° and 70°, it can be controlled sensitively. Therefore, in the field of large-diameter regulation, the application of butterfly valves is very common. In addition, because the structural principle of the butterfly valve is suitable for making large-diameter valves, it is widely used in the field of industrial automation.
The seals of imported pneumatic rubber-lined butterfly valves are made of synthetic rubber materials, which have the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, low cost, etc., and synthetic rubber with different properties can be selected according to different use requirements to meet the working conditions of butterfly valves. At the same time, with the development of polymer polymeric materials such as polytetrafluoroethylene (PTFE) and their filling modification materials, these materials are also widely used in the manufacture of seals for butterfly valves, thereby improving the performance of butterfly valves.
Imported pneumatic rubber lining butterfly valve is a kind of valve with simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy operation and rapid, etc., it has good flow regulation function and closing sealing characteristics, suitable for a variety of corrosive gases, liquids, semi-fluids and various concentrations of acid and alkali salt media.
Imported pneumatic lined butterfly valves are used in many fields, and the following are the main areas:
Chemical production process control: In chemical, petroleum, pharmaceutical, food, papermaking and other industries, imported pneumatic rubber-lined butterfly valves are often used to control the flow, pressure, temperature and other parameters of the fluid to meet the requirements of the production process.
Water supply and drainage system: imported pneumatic rubber lining butterfly valve can be used in urban water supply and drainage system to control the switch and regulation of water flow to ensure the normal operation of the system.
Environmental protection engineering: In environmental protection projects such as sewage treatment and waste gas treatment, imported pneumatic rubber lining butterfly valves can be used to control the flow of fluids and prevent pollution from flowing out.
Energy field: In the energy field of electricity, oil, natural gas and other energy fields, imported pneumatic rubber lined butterfly valves can be used to control the flow and pressure of fluids to ensure the normal delivery and use of energy.
Ship engineering: In ship engineering, imported pneumatic rubber lined butterfly valves can be used to control various fluid systems of ships, such as fuel systems, cooling systems, ballast systems, etc.
