Pipeline various conditions - H44B PN16~PN250 swing steel check valve is applicable to pressure 1.6~25MPa working temperature of -29~+550 DEG C petroleum,chemical, pharmaceutical, chemical fertilizer, the electric power industry and so on, for medium is water, oil, steam, acid medium.

[features]

H44B, swing steel check valve is generated by the pipeline flow of the medium itselfforce automatically turned on and off, is an automatic valve. Check valve for pipeline system, its main role is to prevent the media back, to prevent the pump and drive motor machine inversion, and the container medium discharge. Check valve can also be used for the pipe to the pressure may rise to more than one main system pressureauxiliary system supplies the.
