RRVR/RRVV is used as a closing or pre-setting valve on radiators.
The return valve is equipped with two cones, one for closing and one for pre-setting.
Pre-setting is carried out without draining the system.
The cones are equipped with an o-ring of EPDM rubber and locked with an automatic stopping device in the valve which means the cone cannot be unscrewed unintentionally. Connection 10 even is available in dezincification resistance material.

Unscrew the cap.
Check that the cut-off spindle (the outer) is unscrewed.Pre-setting is done with the help of an allen key (3 mm).
The pre-setting spindle (internal) is unscrewed from bottom position to the number of turns according to the pressure drop diagram. When presetting is complete the cap is screwed back on.
When closing, screw the cut-off spindle (the outer) completely to the bottom with a screwdriver. When opening, unscrew the outer spindle totally.
