1. The Jacketed insulating check valve has good thermal insulation and cold protection characteristics, and can effectively reduce the heat loss of the medium in the pipeline.

2、It is widely used in petroleum, chemical, asphalt, metallurgy, pharmaceutical, food and other systems to prevent the return of high viscosity media that will solidify under normal transport.

3、The jacket is welded with carbon steel pipe and is more pressure-resistant and firm than the cast one.
