English The DWR-206 series is calibrated for falling pressure. This means that the adjustable switching pressure on the scale corresponds to the switching point at falling pressure. The reset point is higher by the amount of the switching difference. Minimum pressure limiter DWR6-206 for hot water, steam, gas, liquid fuels (DWR).
