Jiangsu Lan valve Mine explosion-proof electric valve is widely used in building materials, metallurgy valve, the first valve network chemical, electrical and other sectors, as a compressed explosive pipeline pressure relief devices. Especially suitable for coal grinding systems and storage warehouse use flammable gaseous substances. Simple proof electric gate structure, made of steel welding cylinder and the rupture valve slices. When the system pressure is greater than 0.1 Mpa pressure on the table, explosion-proof valve slice would break itself, which can prevent the explosion of knowledge Daquan valve, in order to ensure personal safety and production.江苏兰 valve General Equipment Co., Ltd. is located in Changzhou City, Jiangsu Province, Yokoyama Town, the transportation is very convenient, welcome new and old customers.
