H44Y chrome-molybdenum steel check valve,chrome-molybdenum steel check valve, check valve

It is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, which belongs to an automatic valve. The chrome-molybdenum steel check valve is used in the pipeline system, and its main function is to prevent the backflow of the medium, prevent the reverse of the pump and its drive motor, and the drainage of the medium in the container. The check valve can also be used to feed the auxiliary system where the pressure may rise to exceed the pressure of the main system. H44Y chromium molybdenum steel check valve is suitable for pressure 1.6~25MPa; Working temperature -29~+550℃ petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions of the pipeline, the applicable medium for water, oil, steam, acid media. The chrome-molybdenum steel material can withstand high temperature and pressure up to 550 degrees.

Chromium molybdenum steel high temperature check valve is suitable for nominal pressure is not greater than PN160, the working temperature is between 425℃ and 570℃ hot water treatment system, thermal power station water vapor pipeline, can use flange connection, welding connection and other forms of connection of a high temperature check valve. The valve body, valve cover and valve disc are located on the sealing surface of the valve body seat.

The body structure of the chromium molybdenum steel high temperature check valve is consistent with the straight-through globe valve, the valve disc can be lifted freely through the medium, when the medium flows, the pressure given by the medium is larger than the gravity of the valve disc itself, so that the valve disc is lifted from the seat sealing surface, the valve is in the open state. When the medium flow stops, the valve disc is no longer supported by the force given by the medium, and automatically falls back to the seat under the influence of its own gravity. The sealing surface of the valve seat is combined with the sealing surface of the valve disc to cut off the medium flow.

Packing of Standard Packing:
