Pulse valve choice
•What is the temperature at the valve; will high temperature seals (eg Viton) be required?
•Are aggressive chemicals in contact with the valve?
•Do we need stainless steel components rather than cast aluminium (standard)
•What will the filter media be? Can we expect higher than usual differential pressures?
•What is the dP required to maintain the dust cake at the appropriate levels?
Waste gas and dew point
•Does the waste gas contain contaminants that may turn to an acid when the system passes through the dew point (eg during shut down periods)?
•Acid condensation on pulse system components will considerably shorten the life of these
