Siem ens Modulating control valves with magnetic actuator‚ PN 16 CA1N4465en
Building Technologies 2018-02-05
Only three-way MXG461S.. valves are supplied. They may be used as straight-through
valves by closing off port «B».
Close off port B with a union fitting.
A CrNi-Steel seal disc with 3 gaskets is part of the delivery.
Union fittings conforming to ISO 49 / DIN 2950 must be supplied
by the installer.

Installation notes
∂ Do not use hemp for sealing the valve body threads.
∂ The actuator may not be lagged.
∂ The MXG461S.. valves are flat-faced allowing sealing with three gaskets provided.
∂ For notes on electrical installation, see «Connection diagram», page 11.
Maintenance notes
The valves and actuators are maintenance-free.
The low friction and robust design make regular servicing unnecessary and ensure a long
service life. The valve stem is sealed from external influences by a maintenance-free
gland.
If the red LED is lit, the electronics must be recalibrated or replaced.
Should the valve electronics prove faulty, the electronics module must be replaced by the
ASE1 replacement electronics module. Mounting Instruction no 35678 is included.
Always disconnect power before fitting or removing the electronics module.
After replacing the electronics module, calibration must be triggered in order to optimally
match the electronics to the valve (refer to «Calibration», page 5).
Under operating conditions within the limits defined by the application data, the
actuator will become hot, but this does not represent a burn risk. Always maintain
the minimum clearance specified, refer to «Dimensions», page 12.
Disposal
The valve is considered electrical and electronic equipment for disposal
in terms of the applicable European Directive and may not be disposed
of as domestic garbage.
∂ Dispose of the valve through channels provided for this
purpose.
∂ Comply with all local and currently applicable laws and
regulations.
Warranty
Application-specific technical data must be observed.
If specified limits are not observed, Siemens will not assume any responsibility.
Valve body, magnetic coil and steel bracket form one integral unit. Dismantling
destroys the magnetic valve.
