[Essential information]
Working principle: the valve has just started, automatic air exhaukt rapid elimination of noncondensable gas in the system, when the steam and thermal condensation of water into the valve cavity, temperature increased with air exhaust device automatically shut down, the floating ball lift according to the change of water level to the opening of the drive lever to adjust the valve seat hole, continuous discharge of condensed water. When the condensed water stops to enter, the floating ball drops by the weight, and drives the lever to drive the valve core to close the drain valve hole.

[Valve features]
Continuous condensation of saturated condensate water, heating equipment will not have the accumulation of water, so as to achieve the highest thermal efficiency.
When the steam pressure is changed, the floating ball drives the lever to automatically adjust the opening of the valve seat hole, and the operation is continuous and the performance is stable.
Exhaust air performance is good, automatic air exhaust device can eliminate non condensing hot and cold gas, no air lock phenomenon, smooth work, no noise.
The sealing performance is excellent, the seal adopts spherical structure, no centralized wear and tear, long service life.
[Adaptive condition]
For the steam heating equipment and condensed water recovery system and the need to quickly remove condensation water conditions, can automatically and rapidly remove condensed water, effectively prevent leakage of steam, and the heating effect is best.
