DJ61Y forged steel low temperature stop valve

First, DJ61Y forged steel low temperature globe valve overview:
DJ61Y forged steel low-temperature globe valve once in the open state, its seat and valve disc sealing surface is no longer in contact, so its sealing surface mechanical wear is small, because most of the globe valve seat and valve disc is easier to repair or replace the sealing element without removing the whole valve from the pipeline, which is very suitable for the valve and pipeline welded into one occasion. The flow direction of the medium through this kind of valve changes, so the flow resistance of the globe valve is higher than that of other valves.

Two, DJ61Y forged steel low temperature stop valve selection principle is:
1, high temperature, high pressure medium pipeline or device should be selected stop valve. Such as thermal power plant, nuclear power plant, petrochemical system of high temperature, high pressure pipeline.
2, pipe road convection resistance requirements are not strict pipe road. That is, where the pressure loss is not considered much.
3, small valves can be selected needle valve, instrument valve, sampling valve, pressure gauge valve, etc.
4, there is flow regulation or pressure regulation, but the adjustment accuracy is not high, and the pipe diameter is relatively small, such as nominal passage ≤50mm pipe road, should be selected.
5, synthetic industrial production of small fertilizers and large fertilizers should be selected nominal pressure PN160 nominal pressure 16MPa or PN320 nominal pressure 32MPa high pressure Angle type stop valve or high pressure Angle type throttle valve.
6, alumina Bayer in the production of desiliconization workshop, easy coking pipe, easy to choose the body separate type, the seat can be removed, carbide sealing pair of direct flow globe valve or direct flow throttle.
7, urban construction in the water supply, heating engineering, nominal through the smaller pipeline, you can choose cut-off, balance valve or plunger valve, such as nominal through less than 150mm pipe road
