Pneumatic lined rubber butterfly valve: a powerful fluid control expert

2025-06-02

Pneumatic lined rubber Butterfly Valve is a star product in the field of industrial fluid control that combines efficiency and reliability. It is powered by compressed air and uses a pneumatic actuator to push the butterfly plate. With a rapid rotation of 90 °, it can accurately achieve valve opening and closing and flow regulation. It has a sensitive response and strong power, especially suitable for complex working conditions that require frequent start stop and quick switching of fluid on/off.

Its core advantage lies in the rubber lining covering the surface of the valve body and butterfly plate, commonly made of natural rubber, chloroprene rubber, nitrile rubber and other materials, which provide a strong protective barrier for the valve. These rubber liners not only effectively resist the erosion of medium concentration acid-base solutions and salt media, but also have good wear resistance and tear resistance. Even under the flushing of fluids containing particle impurities, they can maintain the integrity of the sealing surface and reduce the risk of leakage. Meanwhile, the high elasticity of rubber enables the butterfly valve to tightly adhere to the valve seat when closed, achieving zero leakage sealing and ensuring precise and stable fluid control.

In the municipal water supply and drainage system, pneumatic rubber lined butterfly valves can efficiently regulate the flow of urban water supply and sewage discharge; In the paper industry, when faced with pulp containing corrosive chemicals, it can operate stably to ensure smooth production processes; In the food and beverage industry, rubber liners that meet hygiene standards enable them to safely transport various liquid raw materials and meet food safety production requirements. During use, regularly checking the airtightness of the pneumatic pipeline, cleaning residual impurities inside the valve body, and maintaining the pneumatic actuator can keep the pneumatic Lined Butterfly Valve in the best working condition, providing strong power and excellent performance to safeguard fluid control in industrial production.
