Overview

The worm gear 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 0.6MP. It is generally used for regulating the flow rate of ventilation media in industrial, metallurgical, environmental protection and other pipelines

Product Details

Worm gear ventilation butterfly valveThe sealing ring is made of the same material as the valve body, and its applicable temperature depends on the material of the valve body. The nominal pressure is ≤0.6MPIndustrial, metallurgical, and environmental protection pipelines are generally used for regulating the flow rate of ventilation media.

Its main characteristics are:

1.The design is innovative, reasonable, structurally sound, lightweight, and quickly opens and closes.

2.Small torque, easy operation, effortless and agile.

3.Adopting suitable materials to meet different medium temperatures such as low, medium, and high, as well as corrosive media.
