GESTRA control technology

 NRGS 16-1

Level controlling

In condensate and feed water tanks, etc.

NRG 11-1, PN 6, G1, 4 switching points, PP on/off, flooding, dry run

NRGS 16-1, PN 40, G1, 4 switching points

NRG 11-2, PN 6, G1, 3 switching points, PP on/off, lack of water for low pressure steam boilers up to 0.5 bar

 BAE 46 / BA 46

Desalting valve

Special designs for specific tasks, i.e. low-noise and low-wear level relaxation.

BA(E) 46	PN 40	DN 15-50	C 22.8
BA(E) 47	PN 63	DN 15-50	C 22.8
BA(E) 210	PN 250	DN 25	C 22.8
BA(E) 211	PN 320	DN 25	13 CrMo 4 4
ZK(E) 29	PN 160	DN 50	13 CrMo 4 4

 MPA 46 / PA 46

Blow-down valve

The GESTRA security concept, i.e. boiler and spring pressure ensures a safe close and the downstream radial level nozzle for low-wear operation.

(M)PA 46	PN 40	DN 20-50	C 22.8
(M)PA 47	PN 63	DN 25, 40, 50	C 22.8
(M)PA 110	PN 250	DN 25	13 CrMo 4 4

Surveillance on contamination inleakage

In closed loops (emergency power generators, etc.)

 ORGS 11-2, PN 6, C 22.8

In open circuits and condensate systems

There is a risk of inleakage by oils, grease, etc.:
OR 52-5, PN 10, G 3/8, GG
OR 52-6, PN 10, G 3/8, 1.4580

There is a risk of inleakage by acids, alkalis, etc.:
Electrode LRG 12-1, PN 10, G 11/4
Transmitter LRT 1-6b
Limit switch URS 2
