The inside of our emptying valve be made of high-precision parts, the exhaust mechanism be stable and reliable. In order to ensure that water will not be discharged during the exhaust process, our vent valve uses a special structure-the design of the steams and water separation tray. When the system be running with water or the system pressure be too high and full drainage be required, this automatic pressure relief valve can operate reliably. As long as there be a pressure difference between the inside and outside of the system, the exhaust valve will continue to exhaust. 4 Points 6 Points 1 Inch DN15DN25 Heating Pipes Water Pipes Vent Valves Water Heating Valves/brass Automatic Vent Valves.
