The airtightness of the gate valve is better than that of the butterfly valve, but there are also manufacturers’ butterfly valves that have better airtightness.
The gate valve is large in size and takes up a lot of space.
The butterfly valve is small in size and takes up little space.
When selecting concretely, the temperature of the medium, the sealing of the valve and the packing should also be considered.
The specification stipulates that the butterfly valve with a nominal diameter greater than 50 is used.
Wafer butterfly valve is a national key new product. The high-performance manual butterfly valve adopts a double eccentric and a special oblique cone oval sealing structure. It solves the shortcoming of the traditional eccentric butterfly valve that the sealing surface is still in sliding contact friction at the moment of opening and closing 0°～10°, and the sealing surface of the butterfly plate is separated at the moment of opening, and the effect of sealing when the contact is closed is achieved to extend the service life and maximize the sealing performance.
