Forged Steel Bellows Gate Valve 300LB Large Female Flange
Forged Steel Bellows Gate Valve are mainly used on the pipelines of various systems of thermal power stations, and the medium for cutting or connecting the pipeline media is suitable for: Water, steam and other non-corrosive medium forging steel valves compared with other valve products are characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the seal. Due to the technical characteristics of the performance, the special conditions of the working conditions make the product also form a feature that cannot be replaced by other products.
