How to control my Proportional Solenoid Valve using 0-10V from NI9264

[CADMaster]

Hi

I have 3 proportional Solenoid valves from Cole-Parmer  Cole Parmer DIrect-Lift Propertional Solenoid Valve.

It requires a 0-30 VDC input  for proportional operation. They are suggesting to buy their controller. But its very expensive ( especially since have to buy 3). Is there any driver module (that can be bought) or a circuit that can be made easily that can convert the 0-10V from my NI 9264 module to the 0-30V required to control the valve?

If not what method would anyone here suggest to help control the valve (without the manufacturer's overpriced controller [$ 474 ] and separately sold (shamelessly priced) DB9 serial cable [ for $99] ).

My university lab has the following NI modules - NI 9264 (AO - Voltage ) , 9266 (AO - 0-20mA) , 9375 (DIO). and a cDAQ9187

Can Anyone suggest a circuit that can convert the NI AO voltage to 0-30 VDC?

I am a mechanical engineering fresher and has only basic understanding about electrical/electronics engineering(i.e I'm not qualified or informed enough to design a circuit or choose the components.

P.S To the moderators of the Forum : kindly forgive me if I have posted this question on the wrong board. This is my first time on the NI forum and using NI devices )

The specifications state, that the valve is to be controlled by an analog output voltage signal, between 0-30V DC. It is possible to amplify the signal of the NI-9264 by a factor of x3, probably with a simple amplifier IC and with an external voltage source, or an DC-DC converter. Consult your electrotechnician, if available or search in google, there should be examples.

Regarding the NI-9266, these are special moduls for current-controlled idustrial actuators wich have their own operating concept. You can not use them if you do not have their optional control module.
