Can solenoid valves be used directly as shut-off valves in petrochemical plants?
Thread Content
Can solenoid valves be used directly as shut-off valves to cut off fluid flow, in applications involving small diameters, low pressures, and clean fluids? Are there any relevant standard specifications for this? In the SH3005 selection and design specifications, solenoid valves are mentioned as accessories for control valves
It can be used to directly cut off media such as clean air and water!
No!! It has to be used in conjunction with a manual valve!! If it can’t be closed completely, there’s still a chance of rescue!
It should be feasible. Solenoid valves, together with the appropriate valves, can meet this requirement.
The main function of a solenoid valve is to connect and disconnect! It can certainly be used in petrochemical plants, but the model must match first.
Below DN25, it is feasible when the pressure difference is not significant; generally, its use is not recommended
Alas, what a sad spelling mistake – it should be DN25 or lower
The working conditions are met (such as whether the medium is clean, pressure, etc.), and a correct selection is possible.
I recommend not using solenoid valves as shut-off valves directly, as their failure rate is particularly high. If they break down, it will cause a lot of trouble. For small-diameter applications, I suggest using ball valves – don’t try to save a little money at the expense of facing numerous problems later on! QQ: 928976489 (Your control valve consultant)
These are all empirical statements; as designers, one should base their decisions on the provisions of relevant standards and choose the appropriate methods of use within the limits permitted by those standards. Without such design standards, it is not appropriate to use certain methods arbitrarily.
It is recommended to use solenoid valves with valves, as they are safer and more reliable.
