    The ventilation butterfly valve is made of the same material as the valve body. The applicable temperature depends on the material of the valve body. The nominal pressure is less than or equal to 0.6mpa. Its main characteristics are:

    1, novel design, reasonable, unique structure, light weight, fast opening and closing.

    2, operating torque is small, easy to operate, labor-saving dexterity.

    3, the use of suitable materials to meet the low, medium, high medium temperature and corrosive medium.
