Emergency shut-off valve
Thread Content
Liquefied gas cylinders require emergency shut-off valves to be installed at the inlet and outlet. Which type of valve should be used? If there are any good options, could you recommend specific models and brands? As long as it’s electric.
Electric operation has a slow opening and closing speed, while pneumatic operation is faster; ball valves can be used. You can contact me at QQ179003239
I recommend using a pneumatic ball valve, as it allows for quick switching. My profile picture shows a pneumatic ball valve, haha
It is best to use pneumatic control for quick opening or closing; electric valves are not very suitable for emergency shutdowns!
We all use pneumatic gate valves
I think electric butterfly valves are a good choice; it depends on the diameter though. For smaller diameters, electric butterfly valves work very well. Moreover, butterfly valves inherently have a quick-opening feature
Look at the diameter; however, for quick opening and closing, pneumatic power is still used
The switching speed of electric switches is limited. If an electric drive is necessary, then a electro-hydraulic actuator is required.
Why must it be electric? Is there no gas supply? If the size is not large, I personally think a pneumatic switch ball valve is a good choice. It has a low opening and closing torque, acts quickly, and its cost is not high either.
