Description Blowdown Valve BA46(DN25 PN40) Gestra
Due to the continuous evaporation process in the steam boiler
the density and hence the TDS (= Total Dissolved Solids) concentration
of the boiler water is increased. The TDS level must
remain within the limits specified by the boiler manufacturer
and applicable guidelines. For this purpose a certain amount
of boiler water (= boiler blowdown) is discharged continuously
or periodically. The continuous blowdown valves BA… and
BAE… feature specially designed and wear resistant nozzle
stems that enter concentrically into a system of expansion
chambers which are arranged one after the other, making
the valve well suited for the continuous discharge of boiler
blowdown at very high differential pressures. The continuous
blowdown valves BA… and BAE… are suitable for operation
in steam boiler plants according to TRD 604, EN 12952
and EN 12953.
Function Blowdown Valve BA46(DN25 PN40) Gestra
The continuous blowdown valve BA 46, BA 47 is moved to its
control position by means of the control lever. Use the scale on the
control lever to adjust the required amount of boiler blowdown.
The required amount of boiler blowdown is calculated with the aid
of a formula or read off on a nomogram. The continuous blowdown
valve BAE 46…, BAE 47 is motored to its control position
by means of the actuator EF… The actuator is activated by the
GESTRA conductivity controller KS 90 working in conjunction with
the GESTRA conductivity electrode LRGT 1… or the conductivity
controller LRR 1-5x in combination with the GESTRA conductivity
electrode LRG/T 1… or the conductivity controller LRR 1-40 in
conjunction with the conductivity electrode LRG 16…-40.
The actuator opens or closes the continuous blowdown valve as
