Structure characteristics: 1. new-type SCCV closing system design ensures reliable closedown and long life 2. adjustable discharge temperature by effectively taking advantage of heat and humidity of high-temperature condensate water, and excellent energy conservation effect 3. it can work under the discharge temperature when the pipe network runs and be installed at any angle 4. there’s always condensate water available in front of the valve forming reliable water sealing without leakage of steam 5. water hammer proof with perfect exhaust performance 6. no noise in operation in favor of environmental protection 7. at the beginning of ventilation, the valve fully opens to rapidly expel low-temperature condensate water and air and to greatly shorten the start time for equipment 8. all the internal components are made of stainless steel, corrosion and cavitation erosion proof
