RA-FN valves are designed for use

in 2-pipe heating systems where

circulation through both pipe work

and radiator is pumped. They are

conventional uni-directional valves

without pre-setting; system balancing

must be made using lockshield

valves installed on the radiator return

connection. Please refer to pages 16

and 17 for matching lockshield valves.

A wide range of compression ﬁttings

for copper, PEX and ALUPEX pipe are

available for use with RA-FN valves,

please refer to page 20.

All valves incorporate a gland-seal

assembly that can be replaced without

the need for special tools and without

draining down the system.

RA-FN valves are suitable for use with all

RA2000 sensors and may also be used

with RAS-D

2

and RAS-C

2

sensors. Please

refer to our technical department for

capacity information if using RAS-D

or

RAS-C

sensors.
