Insulated globe valve is mainly used in petroleum, chemical, metallurgy, pharmaceutical and other systems to transport high viscosity media that will solidify at room temperature. The thermal insulation stop valve is especially suitable for the pipeline of chemical and chemical fertilizer industries. The steam in the jacket can prevent the medium from crystallization. Thermal insulation globe valve is widely used in petroleum, chemical, metallurgy, pharmaceutical and other systems.
1. It is simple in structure and convenient in manufacture and maintenance.
2. The working stroke is small and the opening and closing time is short.
3. Good sealing performance, low friction between sealing surfaces and long service life.
