Data Sheet
RA 2000 Series
RA 15/6T & TB
Conversion Valve
Applications:
The RA 15/6T and TB is a special
conversion valve that allows a single
connection point-at the side of the
radiator- to serve as both the supply &
return for a hot water based system. An
example of its application is the
transformation of a 1-pipe steam system
into a hot water based system.
There are two versions to this valve:
RA15/ 6T
Internal bypass allowing for series piping
to the radiators/baseboards. This series
piping provides continuous ow but the
supply water temperature will decrease.
RA15/ 6TB
A conventional two-pipe system where
each radiator/baseboard is supplied. A
traditional supply and return manifold
can be utilized.
With the installation of the RA 15/6T and
TB valves any RA2000 thermostatic
operator or TWA electronic actuator can
be mounted, providing individual
temperature regulation and controlled
comfort for the room.
Features:
• Compact design
• Minimized installation area
• Thermostatic operator or electric
actuator control of valve
• Single entry valve connection to
radiator
• Valve assembly for 1-pipe steam
conversion to hot water
• Alternative method of piping for n
tube or baseboard addition
