High Temperature Check Valve

High Temperature Check Valve


Description of High Temperature Check Valve:

ZECO put the working temperature 450 ℃ > check valve to be high temperature check valve, at the same time the heat level and has five level, 425 ~ 525 ℃ for PⅠ level, 550 ~ 650 ℃ for PⅡ level, 650 ~ 730 ℃ for PⅢ level, from 730 to 816 ℃ to PⅣ > 816 ℃ for P Ⅴ level. When designing high temperature check valve, ZECO pays special attention to the influence of thermal expansion, thermal alternations and mechanical properties of materials on product performance.In order to effectively reduce the stuck or scraped phenomenon caused by the high temperature of the inner parts, ZECO appropriately increased the working space between parts according to these high temperature parameters, so as to ensure that the high temperature check valve can properly cooperate at high temperature within the given working space. High temperature check valve design process should pay attention to the use of temperature shall not exceed the maximum allowable use temperature of the material. According to ASME B31.3 high temperature valve commonly used materials maximum service temperature.In particular, in the actual design of valves to consider the corrosive medium and stress levels and other factors.


Features of High Temperature Check Valve:

1. The seat of ZECO high temperature check valve is designed renewable. When the seat needs to be replaced over time, do not remove the entire valve, just remove the bonnet and replace the seat;

2. The disc of ZECO high temperature check valve can be opened to full open state, the flow resistance of medium can be ignored;

3. ZECO high temperature check valve has Good sealing performance, and in a larger pressure and high temperature also can realized sealed;

4. The trim of ZECO high temperature check valve can withstand the high pressure differences when the valves open/close.
