- Push in the spindle until it pushes against the spring and
then slowly release the pressure on the spring.
▶ For some valves (e.g. GEMÜ 650 and GEMÜ 687) it is ne-
cessary to fit a pressure disc between the threaded ad-
apter and the actuator head. This is included in the re-
quired mounting kits, sometimes with an additional O-ring
(only GEMÜ 650 with normally open and double-acting
control function – code 2+3).
▶ If the pressure disc does not have a groove for a seal, this
will already be inserted in the groove provided at the ad-
apter opening of the actuator head (e.g. GEMÜ 687 with
normally open control function – code 2).
