J41W insulation jacket shut-off valve, also known as the cut-off valve, mainly used in piping systems in chemical, petroleum, pharmaceutical, metallurgical and other industries, the main role is to transport status will be solidified at room temperature, easy to crystallize the media. BJ41W heat shut-off valve between two flanges welding a metal jacket, on the side and bottom of the shut-off valve is provided Weifang steel jacket interfaces valve for injecting steam or other insulation, cold media, to ensure the normal valve media jobs. Shutoff valve connecting flange insulation compared to ordinary freshman to the two shut-off valve to the specifications insulation valves Category: Valves products meet GB, DIN, ANSI and other international standards. Insulation valve further divided into: insulation valve, insulation valve, valve insulation, insulation discharge valve, insulation valves, valve insulation, insulation filters. Insulation valves. Using a wide range of products for large and small caliber, range. Due to the many varieties of insulation valves, detailed structural principle can question the company's technical engineer. Insulation Valve has the following advantages 1, simple structure Shandong valves, manufacturing and maintenance more convenient. 2, the working stroke is small valve opening and closing time is short. 3, sealing Weifang valve, sealing surface friction is small, longer life expectancy. Shortcoming insulation off valve is as follows: 1, fluid resistance, the larger force required to open and closed. 2, does not apply with particles, viscosity, easy to medium coke. 3. Adjust the poor performance. Shandong cast steel valves valve _ _ Valve Co., Ltd. Shandong by Shandong Everbright Everbright valve. Shandong Everbright Valve Co., Ltd.
