jacketed insulation globe valve
technical parameter
product model: bj41w/h
nominal diameter: dn15~250mm
nominal pressure: pn1.6~6.4mpa
applicable temperature: nitric acid
main material: cast steel, stainless steel
product overview
the insulation jacket of the bj41w jacket insulation globe valve is welded between the two flanges of the valve, and the side and bottom of the valve are provided with two connection ports for the insulation jacket. the dc insulation globe valve is especially suitable for pipelines in the chemical and fertilizer industries. the steam contained in the jacket can prevent the medium from crystallizing. it is widely used in petroleum, chemical, metallurgy, pharmaceutical and other systems to transport high-viscosity media that will solidify at room temperature.
product features
1. simple structure, easy to manufacture and maintain.
2. the working stroke is small and the opening and closing time is short.
3. good sealing performance, small friction between sealing surfaces and long service life.
