BCV blowdown control valves
DN15 to DN50 ( " to 2")

Our new range of BCV blowdown control valves are based on the tried
and tested SPIRA-TROL® platform. This new cost effective solution is part
of a range of automatic TDS control systems that limit a boiler’s total
dissolved solids within recommended levels, avoiding excessive blowdown
and heat loss.
As steam is produced the TDS level of water in a boiler
increases. If left uncontrolled TDS levels can exceed
recommended levels and carryover of boiler water along with
steam output will occur into steam and condensate return
systems, causing waterhammer, corrosion and deposits on
heat transfer surfaces.
Accumulation of deposits in control valves, steam traps and on
heat transfer surfaces will adversely affect their performance
resulting in decreased productivity and reduced efficiency.
A Spirax Sarco automatic blowdown control system is designed
to maintain the TDS at an optimum level keeping blowdown to
a minimum, thus maintaining a healthy steam and condensate
system and conserve water and energy.
All products are CE marked and comply fully with the
European Pressure Equipment Directive 97/23/EC. The valve
body can also be provided with certification to EN 10204 3.1
if requested at the point of order placement.
