RA-G valves in ﬂow•

Suitable for use with all RA2000 •

sensors

Available in both vertical angle and •

straight pattern designs in ½”, ¾”

and 1” sizes

RA-G valves are high capacity low

resistance valves for use in conventional

1-pipe heating systems in which water

circulation through the radiator is mainly

by thermo-siphon. In such systems

the circulating pressure available to

overcome the frictional resistance of

the valve and the radiator is extremely

low and is generally insuﬃcient to

overcome the resistance of normal

2-pipe radiator thermostats.

RA-G valves are speciﬁcally designed

for use in such systems and have large

diameter valve cones which deliver high

capacities at low proportional oﬀsets

ensuring that comfort temperatures

can be maintained under all load

conditions.

All valves incorporate a gland-seal

assembly that can be replaced without

the need for special tools and without

draining down the system.
