Vertical fluorine lined check valve is a valve that can automatically prevent fluid backflow, check valve valve valve flap opened under the action of fluid pressure, fluid from the inlet side to the outlet side. When the pressure of the inlet side is lower than that of the outlet side, the valve flap closes automatically under the action of fluid pressure difference, its own gravity and other factors to prevent backflow of fluids. Apply to different work temperature and fluid pipeline, so as not to pipeline or equipment on the media backflow check valve. Can be used in corrosive media to play the role of check to avoid backflow of media.

Lift type fluorine lined check valve for the control of corrosive or strongly corrosive media, the valve body cavity surface covered with PTFE plastic, with high strength, good corrosion resistance; applicable to different work temperature and fluid pipeline, to prevent all kinds of pipeline or equipment on the media backflow of the one-way opening and closing. Applicable to various concentrations of strong alkali organic solvents and other corrosive gases, liquids and media pipeline use.

Single flap swing check valve is a kind of ultra-thin shaped check valve, adopting short structure size and single flap, with O-type sealing ring at the flap, good sealing performance, compared with the traditional swing check valve, this series of valves have no external leakage, can be installed at any position, good sealing performance, small linear vibration, small pressure drop and zero seat wear. Mainly used in water supply system, petroleum, chemical industry, metallurgy and other industrial sectors on the occasion of installation space restrictions.

Double-flap rotary check valve is composed of valve body, valve flap, valve stem and spring and other parts. The valve flap is two semicircles, and spring reset, the sealing surface can be the body surfacing material or rubber lining, the use of butt-clamp connection, compact structure. Due to the short closing stroke of the valve flap and spring loading, the closing speed is fast, which can reduce the water hammer phenomenon. Double-flap swing-open butt-clamp check valve can be installed horizontally or vertically, and can be applied to a variety of fluid media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media.

Stainless steel swing check valve installation position is not restricted, usually installed in the horizontal pipeline, but can also be installed in the vertical pipeline or dumping pipeline. Swing check valve valve flap around the rotary axis for rotary movement, its fluid resistance is generally smaller than the lift check valve, it is suitable for larger caliber occasions. Widely used in petroleum, chemical, pharmaceutical, electric power industry and other working conditions of the pipeline.

Clamped single flap swing check valve is a kind of ultra-thin check valve, which has the advantages of simple structure, beautiful appearance, light weight, easy installation and so on. The flap of the check valve opens under the fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure of the inlet side is lower than that of the outlet side, the valve flap closes automatically under the action of fluid pressure difference, its own gravity and other factors to prevent backflow of fluids. Mainly used in water supply system, petroleum, chemical industry, metallurgy and other industrial sectors for the installation of space restrictions on the occasion.
