Page 5: Important Notes
Usage for the intended purpose BA 46, BA 47: Use the continuous blowdown valves BA 46, BA 47 only for discharging boiler blowdown from steam boilers. Use the equipment only within the allowable pressure and temperature ratings and only if the chemical and corrosive influences on the equipment are taken into account. -
Page 6: Ped (Pressure Equipment Directive)
PED as specified in section 3.3). ATEX (Hazardous Area) The equipment BA 46, BA 47 can be used in potentially explosive areas, provided that the following notes are observed: The service fluid must not generate excessively high operating temperatures. Electrostatic charges that may be produced during operation must be discharged. -
