Pneumatic Wafer Type Rubber lined Butterfly Valve
Summary:
Pneumatic rubber lined butterfly valve refers to the way of high temperature rubber and butterfly valve body vulcanization into one. According to the connection mode, the butterfly valve is generally divided into flange type and wafer type, and according to the requirements of different working conditions, we can choose different performance of the sealing structure (full rubber lined butterfly valve, half rubber lined butterfly valve to meet the different application places to ensure that the pneumatic rubber lined butterfly valve can be used normally. Pneumatic rubber lined butterfly valve is not only anticorrosive, wear-resistant, non-toxic, mildew-proof characteristics, but also has excellent sealing performance. With the application of chemical anticorrosion synthetic rubber in butterfly valve, the use of pneumatic rubber liner butterfly valve has been constantly increasing.

The Appearance and Structure of Butterfly Valve:
Application Scope:
Pneumatic rubber lined butterfly valve is suitable for various types of process pipeline in the liquid and gas (including steam) and other media transport. In the service condition of weak corrosive fluid medium, the butterfly valve is used for two-position switch control or medium flow rate adjustment. Working temperature is generally not more than 180 ºC, and nominal pressure is 1.6 MPa or less. It is widely used in food, medicine, chemical industry, petroleum, electric power, textile, paper, etc.
Advantages:
1. It adoptes the non-pin lining adhesive to ensure the complete isolation of the medium and metal, and improve the reliability of the product.
2. The sealing surface wear resistance is good.
3. It can be installed at any location for convenient maintenance.
4. The seals can be replaced, and sealing can be reliable to achieve two-way sealing zero leakage.
5. The rubber material has no toxicity, and it has anti-bacterial, anti-mold performance. Besides, the product price is one third of the stainless steel valve.
