Gas phase globe valve introduction:
The gas phase manual globe valve of the ammonia station is a shut-off valve used as a manual switch in the ammonia tank of the desulfurization and denitrification project of the power plant. Because the ammonia medium is special, the sealing performance requirements of the valve used are relatively strict. From the valve seal and the stem seal, it is required to meet the zero leakage standard. The valve body and the bonnet connection gasket should be made of gaskets with corrosion resistance not lower than the valve body material. Non-metallic flat gaskets (non-asbestos) can be selected. Gaskets, "metal coated gaskets", "flexible graphite composite reinforcing mats" and other materials. Fillers should be made of [polytetrafluoroethylene" or [flexible graphite". The stem is made of stainless steel and requires heat treatment. The sealing surface is made of babbitt, cemented carbide or polytetrafluoroethylene.
