Operating Instructions Quadax Series Butterfly Valves with Actuator
Retighten both nuts on the stuffing box gland
alternately and in small steps of quarter turns each
clockwise.
If the leakage cannot be remedied in this manner:
repair required: Request spare parts and necessary
instructions from CO-AX.
If the nuts on the stuffing box gland have to be loosened or
unscrewed (counterclockwise):
Danger! Life threatening!
In order to protect the operating personnel against
any danger, please ensure that the line has been
depressurized on both sides of the valve.
Please observe section 2.3 <Particular hazards>.
Check actuating unit and control commands.

Operating instructions: Please watch out for leakages, as a flammable
atmosphere may otherwise develop
Operating instructions: Assembly / disassembly / service only allowed for
a non-flammable atmosphere
Please make sure that the QUADAX valve is earthed. Any existing
attachment parts should be dealt with in line with manufacturer
instructions.
Any heat buildup of valve parts as a result of hot media must be below
ignition temperature
Sound energy can be caused by attachment parts or flow noise
Closing times below the rule of thumb are not allowed (Closing time in s =
nominal width in mm / 100) not allowed
The specific manufacturer operating instructions must be referred to for
any existing attachment parts
When installing additional parts which have not been installed by the
manufacturer or have been explicitly approved for installation, such as
aluminum plates or other fittings, e.g. electric position feedback, a NEW
hazard analysis has to be performed.
Corrosion exceeding 1.5mm may lead to a weakening of pressure parts
and impair the functionality of the valve or may even lead to breakdown.
