RA to RA 2000 Operator Adapter

VIUHA122 © Danfoss 06/07

The older Danfoss RA valve is distinguished by the large silver threaded nut that connects

the operator to the valve.

There are two versions of RA operators:

a) Operator mounts directly on valve with remote bulb/sensor (not shown)

b) Separate remote mounted operator and remote bulb/sensor (shown at left)

RA to RA 2000:

Installation:

1) Remove the existing RA operator (RA-33 shown) from the valve by turning nut counter

clockwise. Although the valve should backseat, for safety, the system should be off.

2) Remove any existing gasket material from the face of the threads.

3) Assemble the adapter to the valve as shown in the diagram. The gasket should be

placed between the valve and the adapter. Tighten the nut sufciently to prevent leakage.

Valve Mounted Operators:

Align the base of the RA2000 operator with the notches on the adapter. Press rmly until

an audible “click” is heard.

013G2922

For tamper resistant operators the Allen screw on the operator must be tightened to secure

to the valve.

In order to use current RA 2000 operators on existing systems with Danfoss RA valves, the adapter

013G8070 must be installed to allow the new operator to t onto the valve.
