BH44H swing heat preservation check valve adopts jacket heat preservation design, the jacket uses carbon steel pipe welding than casting more pressure-resistant firm. The product has good thermal insulation and cold insulation characteristics, and can effectively reduce the heat loss of the medium in the pipeline. Mainly used in petroleum, chemical, asphalt, metallurgy, pharmaceutical, food and other systems, to prevent the conveyance of conventional solidification under the high viscosity medium reflux.

A metal jacket is welded between the flanges at both ends of the BH44H swing heat preservation check valve, and a jacketed connection is installed at the side and bottom of the check valve for the inlet and outlet of steam or heat conduction oil, thus providing the heat preservation effect for the check valve and ensuring the normal flow of viscous media. Mainly used in chemical, petroleum, asphalt, pharmaceutical, metallurgical and other industries in the system pipeline, the main role is to transport at room temperature will be solidified, easy to crystallize the medium.

Product features

1. The swing type thermal insulation check valve adopts the integral jacket structure design, which can keep the insulation evenly and keep the cold evenly.
