Air Vent For Steam: LA series
At equipment startup, the X-element valve is in the open position and large quantities of air are quickly discharged, thereby greatly reducing equipment startup time. When the inflow of steam begins, the X-element valve immediately closes. The valve remains closed as long as the temperature around it is near saturation temperature. As the inflow of air causes the temperature to drop, the valve once again opens and the air is rapidly discharged.
