D341f Fluorine-lined Butterfly Valve Introduction

Lined Butterfly Valve adopts a fluorine-lined plastic-lined butterfly plate with a spherical sealing surface, and is equipped with a silicone rubber liner at the base of the valve seat to adjust the sealing performance of the valve; the valve is easy to operate, has a tight sealing performance, and a long service life; it can be used to quickly cut off or adjust the flow. Suitable for occasions requiring reliable sealing and good adjustment characteristics.
Application of fluorine-lined butterfly valves

The D341F series fluorine-lined butterfly valve adopts fluorine plastic lining technology, and the valve body adopts investment casting, which has high strength and smooth appearance. The flow-through parts in contact with the liquid are all fluorine plastics, so it can be used for a long time in corrosive pipelines and pipelines of any concentration within the range of -50℃ to 180℃. The product is widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the use of severely corrosive media such as sulfuric acid, hydrofluoric acid, phosphorus, acid, strong alkali, aqua regia and other highly corrosive media.

Working principle of fluorine-lined butterfly valve

The working principle of D341F series fluorine-lined butterfly valve is to open or close the valve by rotating the valve disc. The valve disc and the inner side of the valve body are all made of fluorine plastic lining technology. It has the advantages of light switch, small size, reliable sealing, simple structure, convenient maintenance, and wide range of use.

Design features of fluorine-lined butterfly valve
The valve body adopts split type, and the sealing of the valve shaft is controlled by the rotating base surface between the butterfly plate and the valve seat with fluorine rubber, so as to achieve a compact product structure, beautiful appearance, reasonable process and reliable performance. Ensure that the valve shaft does not contact the fluid medium in the cavity, and it is convenient to replace the valve shaft. The valve does not need to be disassembled from the pipeline to complete.
