D941W Electric Ventilated Butterfly Valve

 

 

Product Details

The electrically or pneumatically driven ventilated butterfly valve is equipped with a sealing ring made of the same material as the valve body. Its applicable temperature range is determined by the selection of the valve body, with a nominal pressure ≤0.6MPa. It is generally suitable for regulating medium flow in industrial, metallurgical, environmental protection, and other ventilation pipes.

Its key features include:

1. A novel design with a unique and lightweight structure that enables fast opening and closing.
2. Low torque requirements make it easy to operate and labor-saving.
3. Adaptable materials are used to accommodate low, medium, and high temperatures as well as corrosive media.
