Usage for the intended purpose
a) Steam Traps: BK 7 N, GK , GK , TK , TK 4, UNA 7h, UNA 9, UNA PN 5, UNA Special
Use steam traps only for the discharge of condensed water in steam lines. Observe admissible pressure/temperature ratings and technical
specifications, taking the chemical suitability and corrosion resistance of the pressure equipment into account.
b) Strainers: SZ 6 A
Use strainer SZ 6 A only for fluids of group  (not dangerous) to filter out solid impurities and dirt particles from steam and condensate lines.
Observe admissible pressure/temperature ratings and technical specifications, taking the chemical suitability and corrosion resistance of the
pressure equipment into account.
c) Sightglass: VK 6
Use sightglass VK 6 only for fluids of group  (not dangerous) for visual readings of condensate levels in steam/ condensate lines. Observe
admissible pressure/temperature ratings and technical specifications, taking the chemical suitability and corrosion resistance of the pressure
equipment into account.
d) Intermittent and continuous boiler blowdown valves: BA, BAE, MPA, PA
Use boiler blowdown valves only for removing a portion of boiler water to reduce the total dissolved solids (TDS) concentration or to discharge
sludge in blowdown lines. Observe admissible pressure/temperature ratings and technical specifications, taking the chemical suitability and
corrosion resistance of the pressure equipment into account.
e) Return temperature control valves: BW A
Use return-temperature control valves for fluids of group  and  to control the fluid temperature. Observe admissible pressure/temperature ratings
and technical specifications, taking the chemical suitability and corrosion resistance of the pressure equipment into account.
Chemical Resistance
The wear and corrosion resistance of the equipment has to be verified for the application in question. Special caution should be taken when handling
hazardous materials. In case of doubt contact the manufacturer for specific recommendations regarding the chemical suitability of the equipment.
Safety Note
GESTRA equipment may only be installed by qualified staff.
Qualified staff are those persons who – through adequate training in engineering, the use and application of equipment in accordance with regulations
concerning steam systems, and first aid and accident prevention – have achieved a recognised level of competence appropriate to the installation and
commissioning of the device.
The valve is under pressure during operation.
When loosening flanged connections or sealing plugs hot water, steam, corrosive liquids or toxic gases may escape. This presents the
danger of severe burns and scalds to the whole body or severe cases of poisoning.
Installation and maintenace work should only be carried out when the system is depressurized.
The valve becomes hot or extremely cold during operation. This presents the risk of severe burns to hands and arms. Installation and
maintenace work should only be carried out at room temperatures.
Sharp edges on internals present a danger of cuts to hands. Always wear industrial gloves for installation and maintenance work.
Danger
If required, ask for the Declaration of Conformity covering the product in question at [email protected].
Please note that not all valves have to bear the CE marking.
