Purpose and specification:
NL series wear-resistant throttle valve is a new type of wear-resistant throttle valve developed by our factory under the condition of serious wear of valves in water ash removal system. This series of valves have flexible opening and long service life. They are used as stepless flow regulating valves in the water ash removal system of thermal power plant or two-phase flow pipelines of mining industry and other industries.
