Product Details

Product Overview

The free-floating ball type steam trap (CS41H model) is an automatic valve. It is particularly suitable for applications with low pressure, low drainage volume, and high requirements for temperature stability. It is especially applicable to steam equipment that does not retain condensate. The main working principle of the free-floating ball type steam trap is based on the principle of buoyancy, causing the floating ball inside the valve to move up and down with the water level change, thereby achieving the valve's opening and closing function, that is, the function of draining and blocking steam. It is widely used in various steam pipelines.


Structural features

1. It can continuously drain water, has stable performance, large drainage capacity, and low leakage volume.
2. It can drain continuous saturated water, resulting in less condensate water accumulation in the equipment, faster temperature rise, and stable heating temperature.
3. It has an automatic cold air discharge device, without vapor lock phenomenon, and operates smoothly without noise.
