iQ MINI

Print to PDF

The iQ Mini is a higher mid range proportional valve in iQ Valves family. This modern design is the result of 3 different patented designs by iQ Valves. These valves have a smaller orifice so they can produce less flow rate than the Standard proportional valve at the same pressure. The iQ Mini provides medium isolation using a diaphragm. The iQ Mini is available in two different versions. The Anodized Aluminum version, for regular applications and the Stainless Steel version for medium with corrosive characteristics or for higher temperature applications. Signal Amplifiers are also available to control these valves using a 0 - 5V, 0 - 10V or 4 - 20 mA control signal.

We do manufacture amplifiers to control your proportional valves ! check our range of Signal Amplifiers !

signal amplifiers

Print to PDF

Signal Amplifiers are used to control proportional valves using 0-5V, 0-10V or 4-20 mA control signal. The amplifier boosts the control signal to provide required power to drive the valve. It uses DC power supply to boost the control signal. There is some nominal voltage drop in the amplifier so it is recommended to use a power supply at least 2V higher (min 9 –max 30 V) in voltage rating than that of the valve, to use the valve to its full capacity. All the amplifiers are set in the factory to use with each type of valve. Dither is set to Zero in factory default setting.

How to select a proportional valve for your application

Print to PDF

iQ Valves offers a wide range and variety of proportional valves. Choosing the right valve for your application is important to give you better control over the valve and your process.

Valve selection is based on the pressure differential the valve will see and maximum flow expected at that pressure. Considering these parameters iQ Valves offers three different categories of valves:

1. Miniature valves for ultra low flows – IQ Nano
2. Mid range valves for moderate flows – IQ Mini, IQ Coral
3. Standard valves for high flows – Standard PFCV

The following four charts will guide you in selecting a valve (based on air as the medium). Each of them is divided into different sections by dividing lines. These sections correspond to the category of valve in chart 1 and give the required orifice sizes in charts 2, 3 and 4. Charts 2, 3 and 4 give the required orifice size in Miniature (Chart #2), Midrange (Chart #3) and Standard valve (Chart #4) respectively.

The following examples illustrate valve selection using the charts.

Example 1: Pressure differential across the valve: 50 Psi

Medium: Air

Maximum required flow: 0.6 slpm

To find the valve category use chart 1. Locate a point in chart 1 with pressure and maximum required flow as the co-ordinates (Note Chart 1 has flow in logarithmic scale). In this example the point (with 50 psi and 0.6 slpm as co-ordinates) is in left most section on the chart, which corresponds to Miniature valves.

Chart1

To find the required orifice size in the Miniature valve use chart 2. The point in this chart is in the 0.010 inch orifice size section. Thus appropriate valve for this application is 0.010 inch orifice size Miniature valve.

Chart2

Example 2: Pressure differential across the valve: 50 Psi

Medium: Air

Maximum required flow: 60 slpm

style="text-align:justify; padding-left:6px; padding-right:6px;" To find the proper category of the valve use chart 1. In this example the point (with 50 psi and 60 slpm as co-ordinates) is in middle section on the chart, which corresponds to Midrange valve.

To find the required orifice size in the Midrange valve use chart 3. The point in this chart is in the 0.093 inch orifice size section. Thus appropriate valve for this application is 0.093 inch orifice size Midrange valve.

Chart3

[For the same pressure differential of 50 psi and maximum flow requirement of 100 slpm the point will land in 0.156 orifice area, so the valve for this application will be 0.156 orifice size Midrange valve. Another example would be for 90 psi pressure and maximum required flow of 60 slpm the point will land in 0.062 orifice range, so the valve for this application will be 0.062 orifice size Midrange valve.]

Example 3: Pressure differential across the valve: 50 Psi

Medium: Air

Maximum required flow: 500 slpm

To find the valve category use chart 1. In this example the point (with 50 psi and 500 slpm as co-ordinates) corresponds to Standard valve.

To find the required orifice size in the standard valve use chart 4. The point in this chart is in the 0.375 inch orifice size section. Thus appropriate valve for this application is 0.375 inch orifice size Standard valve.

Chart4

[For the same pressure differential of 50 psi and maximum flow requirement of 700 slpm the point will land in 0.650 orifice area, so the valve for this application will be 0.650 orifice size Standard valve. For 90 psi pressure and maximum required flow of 500 slpm the point will land in 0.316 orifice area, so the valve for this application will be 0.316 orifice size Standard valve.]

Our Standard Proportional valves outperforms other types through its unique Design and Flow control !

iQ STANDARD PROPORTIONAL VALVES

Print to PDF
iQ Valves solenoid-operated proportional flow control valves are unparalleled in the valve industry. Our proportional valve line outperforms other types of proportional valves through unique design innovations. There are no rubbing contact surfaces and hence our valves have low hysteresis, high frequency response (250 Hz), quick time response and long life.

Our valves are direct solenoid actuated poppet type valves. The poppet is attached to the moving part of the solenoid which moves proportionally with applied current. This poppet motion varies the orifice exposure, in turn varying the flow proportionally. The position of the poppet in these types of valves depends on the force balancing between the solenoid, spring force and force due to fluid pressure. Variation in the inlet pressure can change the take-off. Take-off is the point (voltage /current) at which the valve starts flowing. The variation in the outlet (back) pressure can change the displacement of the poppet and hence the overall flow. Pressure balancing of the valve is necessary to make the valve insensitive to these pressure effects.

In some applications isolation of the fluid or medium from the active solenoid parts is required. This isolation can be achieved by using a diaphragm separating the poppet from the active solenoid parts.

Considering these aspects, iQ valves offers the following types of valves in the Standard Valve category:

1. Isolation Inlet Balanced Valve: The main advantage of these valves is medium isolation. These valves are not outlet pressure balanced; however the diaphragm isolation on the inlet side of the valve offers isolation of the fluid or medium from the solenoid parts and offers a small internal volume. In addition, the isolation diaphragm offers pressure balancing on the inlet of the valve; so the variations on the initial take off current of the valve due to inlet pressure variations are minimized. They are useful in the application where the outlet pressure doesn’t exceed 30% of the inlet pressure.

2. Internally Balanced Valve: These valves are pressure balanced and are insensitive to the inlet and outlet pressure. Due to their unique design the take-off of the valve remains the same for different inlet pressures and the poppet displacement doesn’t change with varying outlet pressure. The pressure balancing is achieved using a small internal passage. Therefore these valves do not offer medium isolation.

3. Isolation Balanced Valve: These valves combine the advantage of both inlet balanced and internal balanced valves. These valves are pressure balanced and are insensitive to inlet and outlet pressures. The take-off of the valve remains consistent at different inlet pressures and they can be used at any outlet pressure. These valves offer isolation of the fluid or medium from the solenoid part and offer small internal volume.
