Differences between check valves FT44 and FT43
Thread Content
The FT series of check valves are domestic brands that imitate Spiraax. What is the difference between FT44 and FT43? Which one is good? Seeking advice! Thank you!
FT44, FT43 models – lever float type steam traps. These are supposed to be Spiraax products; the structure and performance of these two models should be exactly the same, with the only difference being the material of the valve body. The valve body of the FT44 model is made of cast steel, while that of the FT43 model is made of cast iron. Additionally, the valve body of the FT46 model is made of stainless steel. It should be noted that the capacity for imitation in China is astonishing; currently, there are domestic-made steam traps of types FT44 and FT43 available on the market, and these domestic steam traps of FT44 and FT43 come in various materials for the valve body
