Short Lead Time for China Marine Bronze Flanged Angle Stop Valves

Short Description:

Insulation Y-type stop valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport high viscosity medium which will solidify at room temperature. The heat preservation jacket is welded between the two flanges of the valve, and two connecting ports of the heat preservation jacket are arranged at the side and bottom of the valve. The valve is especially suitable for the chemical industry, fertilizer industry pipeline, jacket content into the steam can prevent medium crystallization.
