The pilot operated pressure reducing valves of the G4 series are characterized in that the main valve is controlled by a pilot valve, which is itself small in size.The pilot valve controls the opening of the main valve in such a way as to ensure a constant outlet pressure, regardless of the change in pressure at the valve inlet.
The pilot valve provides very precise pressure control, and due to the high speeds, the nominal diameter of the pilot valve will always be smaller than a similar direct-acting valve.
- Maximum inlet pressure: 42 bar
- Operating temperature range: - 20 С to +427 С
- Material: bronze, malleable cast iron, carbon steel, alloy steel.
