What are the main materials of the wafer type gas butterfly valve


In general, the wafer type gas butterfly valve body is mainly made of cast iron, ductile iron, stainless steel and metal alloy, with a certain metal strength. The wafer-type gas butterfly valve butterfly plate is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is 0 °-90 °, which can play the role of flow regulation.

wafer type gas butterfly valve

Butterfly valve mainly through the valve body in the disc-shaped butterfly plate around the axis of rotation to complete the operation of opening or closing the valve, the rotation angle between 0-90 °.

When the rotation angle is 0 °, the valve plate is parallel to the valve body. At this time, the valve is in a fully closed state and stops flowing. When the rotation angle is between 0 ° and 90 °, the valve plate and the valve body produce a certain angle. At this time, the valve is in a semi-open state and can adjust the flow of the medium in the pipeline;

When the rotation angle reaches 90 °, the valve plate is perpendicular to the valve body, the valve is fully open, and the valve flow reaches the maximum value.

Wafer type gas butterfly valve service life, high temperature resistance, wear resistance is also strong, can be used in harsh working environment, widely used in heating, metallurgy, gas supply, and gas, oil, acid and alkali environment.
