Look at the diagram – it’s a problem with the small bypass of the electric valve! ! !

What is the purpose of the small bypass on an electric valve? Is it correct not to install a bypass for this electric valve?
This isn’t a bypass, is it? It looks like a heat tracing tube. Whether a bypass is needed or not depends on its importance; if there is a serious malfunction in the valve that prevents it from functioning, having an alternative route to stop the process for maintenance eliminates the need for a bypass. Otherwise, a bypass is necessary.
There are two purposes for setting up this process flow: one is to serve as a bypass, and the other is for pressure charging. The function of the bypass is to be established according to process requirements. For some special media, it is required that the pressure difference before and after the valve not be too large; this is for specific uses in the production process. For reference. Oh, “no one knows?” Just because you don’t know it doesn’t mean others don’t know it. I wonder if you’d like to know; if I tell you, I’ll see what your level of acceptance is,,,,, When seeking advice, be careful with your wording; frankly, no one is obligated to answer your questions.
It is mainly used to balance pressure, preventing excessive pressure at startup that could prevent the electric valve from opening; thus, a slight bypass opening is provided
It should be a heating pipeline; it serves two purposes: 1) Opening the smaller valve first to heat the pipeline before opening the main valve, in order to prevent water hammer. 2) If the pressure difference between the front and back is too large, the large valve may not be able to open; it serves to balance this pressure difference.
1. When starting up the steam pipeline, the bypass valve is opened first to warm the pipes, as the temperature needs to increase gradually, and the small bypass valve is easy to adjust. 2. Adding a bypass valve can reduce the opening torque of the main valve. 3. If there are two bypass valves, it is usually for high-pressure steam; high-pressure steam pipelines generally have dual valves
Heat pumps are quite common; I haven’t encountered heat pipes yet
This is 9.8 MPa; it’s a small bypass for high-temperature and high-pressure pipeline valves, and there is also an electric version of this small bypass
This is 9.8 MPa; it’s a small bypass valve for high-temperature and high-pressure pipeline valves, a two-hand valve
This is the main steam valve of the steam collection header for the 75t boiler, along with 1 small bypass valve
