What exactly is the relationship between manual valves and electric valves?
With the use of valves, more and more enterprises have begun to use electric valves instead of manual valves. So, what exactly is the relationship between manual valves and electric valves?
As a control element in the fluid piping system, the valve is mainly used to adjust the flow, pressure, temperature and other parameters. There are different driving methods in valves, and valves can be divided into manual valves and electric valves. Manual valves are valves that are driven by human power, while electric valves are valves that are driven by motors or pneumatics. So what are the advantages and disadvantages of manual valves and electric valves.
1.Manual valves.
Advantages: simple structure, cheap and easy maintenance.
Disadvantages: It requires human operation and is difficult to operate for large piping systems.
2.Electric valves.
Advantages: high degree of automation, remote control, high adjustment accuracy.
Disadvantages: **High, requires power supply and control system support.
3.Occasions for manual and electric valves.
Manual valves are suitable for small piping systems and simple fluid control applications, such as domestic water supply systems, small water channels, etc. Electric valves are suitable for large-scale pipeline systems, automated production lines and occasions that require remote control, such as chemical, petroleum, electric power and other fields.
4.Conversion of manual and electric valves.
In some cases, a changeover between a manual valve and an electric valve is required. For example, some older piping systems used manual valves, but as automation increased, they needed to be converted to electric valves. Here are a few things to keep in mind during the conversion process:
1.Confirm the specifications and models of the original piping system in order to select the appropriate electric valve.
2.Considering the pressure, flow and other parameters of the piping system, it is ensured that the electric valve can meet the system requirements.
3.During the conversion process, it is necessary to pay attention to safety issues, such as cutting off the fluid**, emptying the gas in the pipeline, etc.
4.For some special fluids or pipeline systems under extreme conditions such as high temperature and high pressure, it is necessary to choose special electric valves or take corresponding protective measures.
