These operating instructions are designed to offer the user of butterfly valves from the
QUADAX series support in terms of installation, operation and maintenance and warn of any
hazards in particular.
Non-adherence to the following caution and warning notices may lead to
hazards, which in turn may cause the warranty to become invalid.
Please contact the manufacturer for any questions. For addresses please refer to
Attention
section 9.
1 Intended use
Butterfly valves from the QUADAX series are only to be used - following the installation of a
pipeline system (between flanges or by welding) and following the connection of the actuator
to the controls - to close off or pass on media or to regulate flow within the permitted
pressure and temperature limits. These butterfly valves are not recommended for media with
more than just a low amount of solid particulates, they are especially not recommended for
wear-causing solid media.
The maximum pressure (Ps), that may not be exceeded, is specified on the type plate, as is
the temperature range (Ts) that may not be exceeded. The precise relation between
pressure and temperature can be requested from the manufacturer.
When using the valve please ensure that section 2.2 < Safety instructions for the operator> is
observed.
If there is a pressure difference larger than 0.4 bar (liquid agents at ca. 20°C) for
valves used for uninterrupted operation for controlling, please discuss the respective

application limits with the manufacture. Cavitations must be avoided.
2 Safety instructions
2.1 General safety instructions
The same safety instructions apply to valves as to the remaining piping system in which it is
installed, as well as the control system to which the actuator is connected. These instructions
only offer safety instructions that should be observed additionally for valves.
For actuator assemblies please refer to the additional safety instructions in the instructions of
the assembly manufacturer.
2.2 Safety instructions for the operator
It is not the responsibility of the manufacturer CO-AX and, it should therefore be ensured
prior to use of the valve that:
the valve is only used as intended, as described in section 1.
No valve may be operated, whose permissible pressure/temperature range (=
"rating") is insufficient for operating conditions: The permissible range can be
requested from the manufacturer. For materials, pressures or temperatures that have

Non-observance of these instructions can endanger life and limb and may
cause damage to the pipe system.
