The inner cavity of the valve body and the surface of the butterfly plate are fully covered with polytetrafluoroethylene (PTFE) material, which has extremely strong chemical stability and can withstand most strong corrosive media including concentrated sulfuric acid, hydrochloric acid, and nitric acid. The temperature resistance range can reach -196 ℃ to 200 ℃.
-
① Small Opening and Closing Torque, Easy to Operate
The friction coefficient of PTFE material is extremely low (0.02–0.10), and the valve seat has a self-lubricating effect, greatly reducing the resistance when the butterfly plate rotates. Whether manually operated or equipped with pneumatic/electric actuators, it can achieve rapid opening and closing with lower energy consumption.
-
② Clean and Pollution-Free, Suitable for High-Purity Working Conditions
PTFE itself has strong chemical inertness, does not adsorb media, does not release impurities, meets FDA, GMP and other standards, and can be used for sterile media transportation in the food and beverage, pharmaceutical industries, as well as high-purity fluid pipelines in the electronic semiconductor industry.

③ Wide Applicable Temperature Range
Under normal operating conditions, the temperature resistance range is -196 ℃ to 200 ℃, which can adapt to low-temperature cryogenic media and meet the transportation needs of medium temperature corrosive fluids.
