All RB/RBC series boilers are fitted with two, 'Clifton' type (unless otherwise specified) reflex

MAIN STEAM VALVE

Distribution pipework should be run
from the main steam valve on top
of the boiler to the steam delivery
point(s). Care should be taken to
ensure that adequate condensate
drainage and expansion facilities are
provided within the pipework run(s).
To prevent excessive loads being
imposed on the main steam isolating
valve, the pipework should be secured
near the boiler, ensuring adequate
flexibility exists in the pipework
between the steam valve and the
securing point, to minimise any loads
imposed on the valve.
