Fluorine lined gate valve
Overview of fluorine lined gate valve
The product structure is newly designed. All parts in the cavity are made of polytetrafluoroethylene lining structure. The gate adopts a rod mechanism, which solves the inconvenient operation or jamming caused by particles and fibrous media deposited in the screw groove of ordinary concealed rod gate valves. Death and other phenomena, the valve installation position is not subject to any restrictions. Compared with ordinary stem gate valves, this series of products has the following characteristics:
A product has fewer connecting parts and good overall rigidity.
B. The flow interception speed is fast.
C The opening limit mechanism is convenient, flexible and precise.
D. Small in size and beautiful in appearance.
E. Simple operation, labor-saving and convenient maintenance.
F The fluid resistance is small, and the sealing surface is less eroded by the medium.
G. The flow direction of the medium is not restricted, flow is not disturbed, and pressure is not reduced.
The structural length and flange connection are in accordance with the standards of GB12221, ANSI B16.10, GB9113, JB/T79, and ANSI B16.5 respectively.
Applicable media: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media.
Applicable temperature: -80~200℃.
Driving device: manual, electric, pneumatic.
