Programmer-controlled manual or automatic purge valves for the removal of sludge from steam generators for land or naval use, in particular in cases of unsupervised and constant operation according to the TRD 604 directive.

The sludge deposits that accumulate on the bottom of the boiler, during operation, are eliminated with PA and MPA valves.

These valves open briefly and at regular intervals, discharging the accumulated sediments and sludge.

– PA 46 and PA 47 are valves for manual operation (actuator can also be mounted in one second time).
– MPA 46 and MPA 47 are valves with membrane actuator with compressed air or pressurized water).
