Valve purpose: Eccentric hemisphere valve, also known as C-type ball valve, is to make the valve unblocked or blocked by rotating the hemisphere. The switch is light and small in size. It can be made into a large diameter. It has reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often close1
Brief introduction: Because the valve stem opening or closing stroke is relatively short, and has a very reliable cut-off function, and because the change of valve seat opening is in direct proportion to the stroke of valve disc, it is very suitable for flow regulation. Therefore, this type of valve is very suitable for cutting off or regulating an1
Overview of BZ41H insulated gate valve: The insulated gate valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems. The jacket of the valve is welded between the two flanges of the valve. The side and bottom of the valve are equipped with the connection port of the jacket. The jacket can freely flow through stea1
Overview of D363H/W Butt Welding Hard Seal Butterfly Valve: D363H butt-welding hard-sealed butterfly valve is widely used in metallurgy, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425℃. It adopts precision J-shaped elastic sealing ring and three-eccentric1
