Hydraulic quick shut-off valve

Product type: KD743X, KD743W    Nominal pressure: 0.10MPa (0.25)  Strength test pressure: 0.15MPa (0.375)  Sealing test pressure: 0.11MPa (0.275)  Applicable temperature: ≤200℃  Applicable medium: heating furnace gas, blast furnace gas, converter gas, etc  One-way opening and closing time: DN≤1200, S≤2 seconds; DN≥1400 S≤3.5 seconds  Purpose and characteristics  The quick shut-off valve is a specialized device for the TRT blast furnace pressure recovery power generation system. It is installed in series with the gate valve at the front of the axial flow fan inlet. When there is an abnormal condition in the power generation system, it can quickly shut off the gas medium circulating in the pipeline, thereby protecting the safety of the TRT system equipment. It can also be used in other industrial pipelines to cut off the flow of gas medium. Its main features are:  (1) The valve uses rolling bearings, which are flexible in…
