Standard PFCV (Isolation Inlet Balanced)
Print to PDF
These are isolation inlet balanced proportional valves available in anodized aluminum and stainless steel. 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 applications where the outlet pressure doesn't exceed 30% of the inlet pressure. Signal Amplifiers are also available to control these valves using a 0 - 5V, 0 - 10V or 4 - 20 mA control signal.
