     Thermostatic free float steam trap is an automatic valve, especially for low pressure, low displacement and high temperature stability requirements, should not be stored with condensing water steam equipment is more applicable. Free float steam trap's main working principle is based on the principle of buoyancy, so that the valve body float with the water level changes for lifting movements to achieve the valve opening and closing, that is, the role of drainage gas barrier. Widely used in a variety of steam pipes.
 

Structural features
 1, continuous drainage, stable performance, large displacement, small amount of leakage. 
 2, to row continuous saturated water, to make the device less stagnant water condensate, heating fast, heating temperature stable. 
 3, automatic exhaust air device, no gas lock phenomenon, work balance, no noise.
