Page 4: Operation
Operation Principles of air discharge: 1. Start-up Air Discharge Initially, the X-element is open and air in piping is quickly vented, significantly shortening equipment start-up time. 2. Closed Position When steam flows in, the increased temperature causes the X-element to close immediately. If the temperature around the X-element is near steam saturation temperature, the vent will remain closed. -
