1, exhaust air and water: line pressure or gravity make valve open, quickly ruled out air and water, shorten the heating time.
2, vapor barrier: into the valve cavity of the steam make double metal element bending produce heat tension, and overcome the pipeline pressure is close valve ball. Hot tensile with corresponding saturated steam curve changes. Therefore, in the pressure range can work effectively.
3, discharge condensate: condensate gradually gradually reduce the bimetallic element hot tensile, make the discharge orifice opened up, condensed water clear without let or hindrance emissions.
4, start-stop valve action: valve ball in line produce return, the immediate closure of hydrophobic valve outlet, without additional device.
