The structure of fluorine-lined ball valve is full-bore floating ball type. It is mainly used to cut off or connect corrosive media in pipelines.

Fluorine-lined gate valve is a kind of valve. The opening and closing part of the fluorine-lined gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

The opening and closing part of the fluorine-lined globe valve is a plug-shaped valve disc, the sealing surface is a plane or a conical surface, and the valve disc moves linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem rises and falls, and the handwheel does not rise and fall), and there is also a lifting rotating rod type (the handwheel rotates and lifts together with the valve rod, and the nut is arranged on the valve body). The globe valve is only suitable for fully open and fully closed, no adjustment and throttling are allowed.

Fluorine-lined check valve is also called check valve. The function of this type of valve is to allow the medium to flow in only one direction, and to prevent flow in one direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincident valve flap of the valve flap act on the valve seat, thereby cutting off the flow.

The butterfly plate of the fluorine-lined butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open.

The fluorine-lined diaphragm valve is a special form of shut-off valve that appeared in the 1920s. Its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts, so it is called a diaphragm valve.

The fluorine-lined plug valve is a valve that uses a plug body with a through hole as the opening and closing part, and the plug body rotates with the valve stem to realize the opening and closing action. The plug valve opens and closes quickly and the fluid resistance is small.

The fluorine-lined sight glass is used to observe the flow and color change of the unit fluid in the pipeline or equipment, and directly monitor the chemical process flow.

Fluorine-lined discharge ball valve is suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidants at -50℃～150℃. FEP is also suitable for various concentrations of strong alkali organic acids. Solvents and other corrosive gases and liquids are used in pipelines.

The fluorine-lined filter is used to remove impurities in corrosive media and protect the normal use of pumps, valves and other equipment. Generally, the water network is 20-60 mesh/cm2, and the ventilation network is 40-100 mesh/cm2, and the oil-passing network is 100-480 mesh/cm2. It can be configured according to the medium. Since the inner wall of the filter and the filter screen are made of PTFE with strong corrosion resistance, this product is widely used in various corrosive pipelines.
