Overview

The ventilation butterfly valve is made of the same material as the valve body and processed into a sealing ring. Its applicable temperature depends on the material of the valve body, and the nominal pressure is ≤ 0.6MPa. It is generally used for regulating the flow rate of ventilation media in industrial, metallurgical, environmental protection and other pipelines.

Product Details

1、 Product details:

Product features: The Shangming brand ventilation butterfly valve is made of the same material as the valve body and processed into a sealing ring. Its applicable temperature depends on the material selected for the valve body, with a nominal pressure of ≤ 0.6MPa. It is generally used for regulating the flow rate of ventilation media in industrial, metallurgical, environmental protection and other pipelines. Its main characteristics are:
1. The design is innovative, reasonable, structurally sound, lightweight, and quickly opens and closes.
2. Small operating torque, easy to operate, labor-saving and agile.
3. Adopting suitable materials to meet different medium temperatures such as low, medium, and high, as well as corrosive media.
