Abstract
This valve is attached to steam piping systems, compressed air piping systems, or gas piping systems, and automatically discharges only condensed water without allowing gas to escape. Its size is approximately 210 mm from side to side in the front view. The cylindrical parts that protrude to the left and right at the top in the front view are connected to the piping. Gas and condensed water flow in from the left cylindrical part, and the condensed water is automatically discharged from the right cylindrical part as a float (not shown) located inside rises and falls.
