DatasheetDWR pressure limiters are particularly suitable as pressure limiters for fuel gases (DVGW worksheet G 260) and liquid fuels (e.g., heating oil), as well as for steam systems according to TRBS and hot water systems according to DIN EN12828, systems according to DIN EN12952-11 and DIN EN12953-9. The DWR-205/-206 is used to limit maximum and minimum pressures and features an internal locking mechanism. Important: When selecting the limiter, it must be decided whether the device is to be used for maximum or minimum pressure monitoring. The direction of operation cannot be reversed on the pressure limiter. It has a robust housing made of seawater-resistant die-cast aluminum.
Features & Benefits:
- The DWR-205 series is calibrated for rising pressure. This means that the adjustable switching pressure on the scale corresponds to the switching point at rising pressure.
- The reset point is lower by the amount of the switching differential. (See also page 23, 2. Calibration at the upper switching point).
- 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 differential.
- Burst pressure for all types ≥ 100 bar, tested by TÜV.
- The sensor is of “special design” through testing with 2 million cycles.
