actuator valves v/s global valves

[Dost]

I am working on  two phase multiple flow rig.The rig has several mechanical globes valves mounted on two inch diameter pipe.these valves are being used to control the level of tank.

I want to control these valves via Labview so i need to replace them by their electronic counter parts. need you suggestion to replace thise globe valves so that they can be controlled by

Labview and DAQ card.the pressure rating for these valves are PN30 bar.Any comments.Which valves  should i use to replace them.I came to know that actuator may be one of the options.

but i do nt know how to use them with labview.Which  DAQ card shoud I used to interface with these actuator.I am using  PC MIO E series card.is it enough to be used with actuator.any help

Hi Dost,

I don't have much experiance with this technology, however I have done a quick Google search and found this Here you could also try this Here

Hi Dost
I think you need to provide more information: with a 2inch diameter pipe what flow rates are you expecting, valve characteristics,
temperature parameters,also pressure, does viscosity have a bearing ?
Not familiar with globe valves but I daresay you could replace them with 'motor driven valves ie stepper motor etc.

There are various methods of interfacing,which you need to invesigate.An example is to use  5V TTL level to 'switch' a relay to enable a motor
to drive  valve open or shut.
The more details provided the more solutions possible.
