Submittal Sheet

Specification
The thermostatic radiator valve assembly shall be
selected to maintain room temperature within ±1°F.
The operator shall be of a bellows design with a vapor
or liquid charge and shall be connected to the valve
via a snap-on fast mounting system or secured by an
Allen screw. The thermostatic operator shall be
capable of temperature adjustment between 45° and
86°F (7 and 30°C) and be locked and limited by the
use of limiting pins or internal mechanism.
The valve shall be of nickel plated brass
construction with a fully replaceable packing gland
capable of replacement while the system is in
operation. The valve disc shall be constructed of
EPDM, capable of withstanding 250°F (121°C).
The thermostatic radiator valve shall be Danfoss or
an approved equal.
Construction
Temperature settings
The numbers reflected on the
dial (1-5) correlate to available
temperature positions. The
lowest setting (*) provides
frost protection and maintains
the room temperature at
approximately 45°F.
Mounting of Operator
013G8250 & 013G8252
Snap on attachment
Rotation of the base
retracts teeth allowing the
operator to be pushed and
mounted onto the valve
013G8240 & 013G2922
Allen key requirement
Firmly seat the operator to
the valve then tighten
operator with an Allen key
Wall mounted versions
Allen key requirement
Firmly seat the remote
operator to the valve then
tighten remote operator
with an Allen key
Operator Orientation
The valve mounted built-in
thermostatic operator
(013G8250) should not be
installed in a vertical
orientation. The result will
cause the operator to close
prematurely. The operator should be installed in a
horizontal position allowing proper air flow across the
sensing element. If the operator is unable to be
reoriented, a different thermostatic operator should
be selected with a remote sensor.
Limiting and Locking Operator Setting
All RA2000 operators have the ability to limit or lock
the temperature range or setting. For built-in style
operators pins are inserted on the back of the
operator, while wall mounted versions require the
face plate to be removed and tabs located on the dial
to be set.
Theft protection
To prevent the removal of standard built-in operators
(013G8250 and 013G8252) from the valve an optional
anti-theft protection clip is inserted at the base of the
operator.
