Continuous Blowdown Valves

Continuous blowdown valves

Continual evaporation in the steam generating unit increases the dissolved solids content of the boiler water.

If this is not kept to a low level, sediment and scale builds up throughout the steam system.

This has a number of effects including:

Reduced effectiveness of heat transfer increasing fuel costs
Increased maintenance shutdown and costs due to the requirement to service scaled up products
Production efficiency decreases as heat transfer to critical process becomes less effective

GESTRA's BAE valves have a wear-resistant nozzle with a geometry and design that are specifically for continuous blowdown applications.

It is a reliable solution that can handle arduous, continuous boiler blowdown applications at very high differential pressures.

Our solutions will help you to...
