BD641H type thermal insulation butterfly valve

1. Structure and characteristics

The thermal insulation butterfly valve has good thermal insulation and cold preservation characteristics, and the valve diameter is the same as the pipe diameter, and at the same time, it can effectively reduce the heat loss of the medium in the pipeline.

2. Purpose

Insulation butterfly valves are widely used in various systems such as petroleum, chemical industry, metallurgy, pharmaceuticals, etc., effectively reducing the heat loss of the medium in the pipeline and preventing the appearance of crystallization and solidification of the medium. The function of the thermal insulation butterfly valve is that when the temperature is high or low, the substance in the thermal insulation butterfly valve will have a thermal insulation effect on the medium, so that the medium will not condense or stick to the inside of the valve body, so that the opening and closing of the valve can operate normally.
