GKV-710R fluorine lined butterfly valve designed to resist corrosive chemicals
The GKV-710R series is midline fluorine lined butterfly valve is a special valve designed specifically for highly corrosive media, using a midline symmetrical structure and fluoroplastic (such as PTFE, FEP, PFA, TEFLON) lining technology.
The valve body cavity, valve plate, and valve stem contact areas are lined with fluoroplastics such as PTFE (polytetrafluoroethylene) and FEP (fluorinated ethylene propylene copolymer), which are resistant to strong acids (sulfuric acid, hydrochloric acid), strong alkalis (sodium hydroxide), organic solvents, and oxidizing media, and are suitable for pH values ranging from 0 to 14.
Adopting molding or injection molding technology to achieve full lining of the flow channel, avoiding contact between the medium and metal, and eliminating the risk of corrosion and leakage.
Wear resistance and aging resistance: the friction coefficient of fluoroplastic layer is low (PTFE ≈ 0.05), it is resistant to medium crystallization and particle erosion, and its service life can reach 3~5 times of that of ordinary valves.
The unique design of GKV-710R fluorine lined butterfly valve
The GKV-710R fluorine lined butterfly valve is engineered for reliable flow control in highly corrosive environments. Its fluorine lining (PTFE/FEP/PFA/TEFLON) provides excellent chemical resistance against acids, alkalis, seawater, and various industrial media, ensuring long service life and stable performance. The valve features low opening and closing torque, reducing wear on the actuator and enabling energy-efficient operation.
Designed with an ISO5211 standard mounting platform, the GKV-710R offers flexible drive options including manual handle, pneumatic actuator, or electric actuator, making it adaptable to diverse automation requirements. The bi-directional sealing structure ensures zero leakage, while the compact, lightweight design facilitates easy installation in pipelines with limited space.
