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.
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鈥檛 exceed 30% of the inlet pressure.
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.
