Important Notes
Usage for the intended purpose
BA 46, BA 47:
Use the continuous blowdown valves BA 46, BA 47 only for discharging water from steam boilers to
ensure the correct water conditions in the boiler. Application in pipes within the admissible pressure/
temperature ratings, taking the chemical and corrosive effects on the pressure equipment into account.
BAE 46, BAE 47:
Use the continuous blowdown valves BAE 46, BAE 47 only in conjunction with the control equipment
KS 90, LRR -40 or LRR -5, LRR -6 for discharging water from steam boilers to ensure the correct
water conditions in the boiler. Application in pipes within the admissible pressure/temperature ratings,
taking the chemical and corrosive effects on the pressure equipment into account
.
To ensure the safe operation of the BAE 46, BAE 47 mount only actuators that are explicitly specified by
GESTRA onto the control valve. Specified and approved actuators are:
ARIS EF 0.5, ARIS EF , ARIS EF - and ARIS EF -40.
Danger
The valve is under pressure during operation.
When loosening flanged connections, sealing plugs or stuffing boxes, hot water and
steam may escape.
The valve becomes hot during operation.
This presents the risk of severe burns to hands and arms.
Before servicing the valve or loosening flanges, stuffing box connections or sealing plugs
make sure that all connected lines are depressurised (0 bar) and cooled down to room
temperature (0 °C).
During operation moving internals can pinch one‘s hands or fingers. Do not touch
moving parts! The continuous blowdown valves BAE 46, BAE 47 are remote controlled
and can open and close very abruptly.
The terminal strips of the actuator EF ... are live during operation.
This presents the danger of electric shock.
Cut off power supply before fixing or removing the equipment.
Sharp edges on internals present a danger of cuts to hands. Always wear industrial
gloves when replacing the packing, valve seat or valve plug.
Safety note
The equipment must only be installed and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified staff who – through adequate
training – have achieved a recognised level of competence.
