Four features of the general-type bimetalic-type trap valve
2.1 Exhausting air and water:the pressure or gravity of the pipework cause the valve opened, quickly exhaust air and water,and shorten heating-up time.
2.2 Steam-resistance: the steam rushing into valve cavity cause bimetalic element to bend and generate heating tension, and overcome the pipe pressure to shut off the ball.
The heating tension changes according to the corresponding saturated steam curve. Therefore, it can be effectively work within its pressure range.
2.3 Discharge condensed water: the condensed water gradually reduces the heating tension of the bimetalic elements, making the discharge-hole gradually open, so the condensed watercan be discharged unblocked and unimpeded.
2.4 Function as check valve: the valve ball can produce backflow in the pipeline, so it can immediately close discharge-hole, without any additional device.
