●General Information
High temperature cut-off valve is suitable for the secondary use of waste heat of boiler, furnace, blast furnace in building materials, mining, power, glass, light industry and other industry and waste gas and smoke pollution control of a variety of hot blast pipe. It is ideal equipment for energy-saving and high temperature gas switching.
●Structure Characteristics
High temperature Cut-off valve adopts stainless steel and carbon steel welding. It is double layer structure, the inner lining has a flame retardant, heat resistance materials. It has high temperature resistance, high efficiency, perfect structure, scientific and reasonable, flexible start and stop, convenient operation, etc.
The drive mode is split type and drive device is not subject to any form of control so that can be installed with the customer's needs. Drive form can be divided into winch lifting (switch signal), electric actuators lifting (4 ~ 20 mA current signal), electro-hydraulic, electric push rod (switch signal).
