Product Usage
H44H, H44Y type PN16 ~ PN250 swing check valve for pressure 1.6 ~ 25MPa working temperature -29 ~ +550 ℃ petroleum, chemical, pharmaceutical, fertilizer, power industry and other conditions of the pipeline, the applicable medium is Water, oil, steam, acidic medium and so on.
Features
H44H, H44Y Swing Check Valve is automatically opened and closed by the force generated by the flow of medium itself in the pipeline, which belongs to an automatic valve. Check valve for piping systems, its main role is to prevent media backflow, to prevent the pump and its drive motor reversal, as well as the container media release. Check valves can also be used on lines where the pressure may rise to a level above the pressure of the main system auxiliary system.
