1. The working principle of this series of drain valves is based on the principle of thermal static force, with continuous discharge of condensed water and non condensed steam, smooth flow, and no carried superheated steam. 

2. The drainage temperature of the drain valve can be adjusted online on site according to different working conditions. 

3. The drain valve body comes with a pre filter to avoid blockage. 

4. The condensate drainage temperature is around 95 ℃, and the core components are made of 316L stainless steel, suitable for steam use in medium pressure pipelines below 450 ℃ and 6.0MPa.

5. Allow high back pressure, with a maximum allowable back pressure of 85% of the pre valve pressure, which is beneficial for condensate recovery
