Steam Trap BK 15 PN 40 DN 40, 50 DN (1 ½", 2")
Thermostatic steam trap with corrosion-resistant Thermovit (Duo stainless steel) regulator unaffected by water hammer. The Thermovit regulator can be adjusted from the outside. With integral strainer and non-return valve action. Asbestos-free body gasket (graphite). Installation in any position. The steam trap is adjusted at our factory to discharge condensate with virtually no banking-up. More undercooling (banking-up) can be set manually from the outside during operation.

Level switch NRS 1-51
The level switch NRS 1-51 is used in conjunction with level electrodes NRG 1...-.. as high level alarm in steam boilers and (pressurised) hot-water plants. A high level alarm prevents the water level from exceeding the preset max. water level (HW) and for this purpose switches off e. g. the feedwater supply.

Electropneumatic smart positioner - a guide to HART® functionality SP500
DD files have been created specifically for the SP500 HART® smart valve positioner. These files provide access to the complete command set through a user-friendly menu structure, allowing both remote calibration and control of the positioner. The device description is stored on the host. Once the actuator is identified, the file is automatically loaded and communication with the actuator may commence.

Monitoring logic unit SRL 6-60
When LW/HW level electrodes are installed in external level pots, it is essential to monitor the periodic purging of the connecting pipes. A monitoring logic unit is required for each level pot. For purging, the connecting pipes are individually shut off and reopened in succession, and the level pot is drained. The SRL 6-60 monitoring logic unit monitors compliance with the set times and the sequence of valve operations.

Level electrodes NRG 16-61, NRG 17-61, NRG 19-61, NRG 111-61
NRG 1x-61 level electrodes are used in conjunction with the URS 60 / URS 61 safety control unit as safety high-level limiters for pressurised steam and hot-water plants. ■ Safety high-level limiters prevent the defined maximum high water (HW) level from being exceeded, e.g. by switching off the feedwater supply. ■ Visualisation and operation take place via the URB 60 operating unit or the SPECTORcontrol.

Indicateur de niveau NRS 1-50 Appareil à DEUX électrodes
Associé aux électrodes de niveau NRG 1...-.., l’indicateur de niveau NRS 1-50 est utilisé comme limiteur de niveau d’eau pour les installations de chaudière à vapeur et à eau surchauffée. Les limiteurs de niveau d’eau coupent le chauffage lorsque le niveau d’eau le plus bas défini (NB) n’est pas atteint.
