Ventilation Butterfly Valve
Ventilation butterfly valve is used for controlling and adjusting gas flow in pipelines for industrial, metallurgy, power station, or other applications. The applicable temperature varies according to the valve materials and users' actual needs. The nominal pressure of the valve is no more than ≤0.6MPa.
Main Features
1. The ventilation valve features unique structure, light weight, and quick closing and opening
2. It is easy-operated with little operating torque
3. We will choose different materials for the valve to make it applicable for medium of different temperature and corrosion degree
