Product Overview

Vertical Fully Lined Lifting-Type Check Valve can automatically prevent fluid backflow, check valve flap opened under the pressure of fluid. When the pressure of the inlet side is lower than that of the outlet side, the valve flap closes automatically, its own gravity and other factors to prevent backflow of fluids. Apply to different work temperature and fluid pipeline. Can be used in corrosive media to play the role of check to avoid backflow of media.

Performance Characteristics

Vertical Fully Lined Lifting-Type Check Valve, adapted to vertical pipeline installation, suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and a variety of organic acids, strong acids, strong oxidizing agents, FEP lined check valve is also suitable for a variety of concentrations of strong alkali organic solvents, and other corrosive gases, liquids and media pipeline use.

Vertical Fully Lined Lifting-Type Check Valve without any additional energy devices, reduce operating costs for general conditions and special conditions of abrasive or corrosive media, unique design features allow solid particles to pass through the valve, and even the use of the body of the flexibility of the solid particles wrapped to ensure the sealing, good effect of the backflow, the use of the elasticity of the fluorine plastic itself and the role of the reverse back pressure, sealing and reliable, especially the new type of curved Shape valve mouth, further increase the sealing, reduce the amount of leakage or no leakage, work through the internal and external pressure difference to naturally realize the opening and closing, is a strong corrosive media and power station desulfurization.
