The NS-type E valve is a valve that retains the advantages of the NK valve's dust removal function while being more compact, requiring less water during sealing, and being lighter in weight.
- Due to its special diaphragm structure, it can remove dust adhered to the seat surface and is widely used for valves for by-product gases such as blast furnace gas (BFG), coke oven gas (COG), and converter gas (LDG) generated from equipment in steel mills that contain a large amount of dust. - It allows for non-leak, complete shut-off and can also be used as a water seal valve to ensure further safety. - Developed and launched in 2014, there have been no significant trouble reports after delivery to domestic steel mills. - When used as a water seal valve, it does not require a large installation space like a V-shaped water seal pipe, and the amount of water needed for sealing is minimal, making it environmentally friendly and allowing for simplification of foundations, etc.
