RA-N valves with pre-setting for •
larger heating systems
RA-N valves in flow•
RA-N valves are easily recognised •
by a red cover cap
Available in vertical angle, •
horizontal angle, side angle and
straight pattern versions in 3/8”,
1/2”, and 1” sizes
RA-N are uni-directional valves with
integrated pre-setting. Pre-setting
allows the commissioning engineer to
precisely set the flow rate through the
valve by adjusting the valve capacity
to match the radiator heat output
requirement.
Pre-setting is carried out by setting a
calibrated orifice within the valve. The
setting is achieved by turning a scale
located in the top part of the valve body.
The setting mechanism is concealed
once the thermostat sensor is fitted.
This type of pre-setting is significantly
more accurate than that possible with
conventional lockshield valves. When
pre-setting valves are used the role of
the lockshield valve is simply to provide
isolation for radiator removal.
