Mounting notes
Mounting and operating instructions are printed on the actuator and on the electronics
module.
The valve may only be used as a mixing or throughport valve, not as a diverting
valve. Observe the direction of flow!
A strainer should be fitted upstream of the valve. This increases reliability.

Installation notes
• The MXG..461.. valves are flat-faced allowing sealing with the gaskets provided with
the ALG..3 set of 3 threaded fittings.
• Do not use hemp for sealing the valve body threads.
• The actuator may not be lagged.
For notes on electrical installation, see "Connection diagram".
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.
