What is the difference between a free-floating ball steam trap and a lever-floating ball steam trap?

There is a difference; you can tell just by looking at the name. As for water rejection capacity, it depends on the operating conditions; a suitable diameter, back pressure, and so on need to be selected

The discharge capacity of lever-type float hydrovanes is quite high. . .

A free ball steam trap uses the ball itself as the valve element, while a lever ball steam trap employs a dedicated hardened valve element. Therefore, although free-floating ball hydrophobic valves are easy to manufacture with a low entry barrier ； However, the hardness, roundness, diameter accuracy, and surface roughness of the ball all affect the sealing performance of the steam trap, which makes it difficult to achieve optimal results. It is easier to manufacture compared to lever float hydrostatic valves. 2. By utilizing the amplifying effect of levers, the displacement and maximum pressure difference of the lever-mounted float are higher than those of a free float. 3. Due to the mechanical dead zone, the lever float responds more slowly than a free float; therefore, an inappropriate selection of this type can lead to steam leakage. 4. For example, when lever float balls are used for steam cylinder drain valves, their lifespan is quite short. It is also a mistake to use a free floating ball for heat exchangers with high water rejection. Specific analysis of different application conditions. 5. Hangzhou Watt believes that only one Japanese company does a good job with free-floating balls, while reputable manufacturers generally produce high-quality lever-floating balls. This is why there is only one imported brand that produces free-floating balls. However, the application of free-floating balls can basically replace the Watt inverted barrel hydrophobic valve. 6. Both lever float and free float hydrostatic valves should be equipped with built-in thermostatic vent valves; otherwise, air locking is likely to occur. The quality of the exhaust valve is also very important.
