Introduction:
PTFE seat butterfly valve for midline butterfly valve, with simple structure, small and light, easy to disassemble; 90 degree open and close, quick switch. Small operating torque, lightweight labor saving; Good sealing performance, long service life, can achieve zero leakage; Choose different parts material, can be applied to a variety of media; Flow characteristic is similar to straight line, good regulating performance.
Application:
PTFE seat butterfly valve is suitable for: chemical, petrochemical, smelting, medicine, food and other industries SO2, steam, gas, ammonia, CO2 gas, salt water, lye, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media on the pipeline as a regulator and closure device.
Description:
PTFE seat butterfly valve PTFE seat material with high chemical corrosion resistance, such as in concentrated sulfuric acid, nitric acid, hydrochloric acid, and even boiling in aqua aqua, its weight and performance are unchanged. Ptfe does not absorb moisture, does not burn, is extremely stable to oxygen and ultraviolet light, so it has excellent weather resistance
