Notes
Safety
DANGER
There is a risk to operating personnel and de
vice when working on th
e unit
Failure to comply with these safety notes can result in personal injury and damage to
property from pipe pressure, electrical voltage, or device in operation.
 Note the following when servicing a valve/actuator:
● Switch off both pump and operating voltage.
● Close shutoff valves.
● Release pressure in the pipes and allow them to cool down completely.
● Disconnect electrical connections from the terminals as needed.
● The actuator must be properly installed or manually adjusted prior to recommissioning
the valve.
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
● Observe national provisions and comply with the appropriate safety regulations.
Engineering
We recommend installing the valve with spring return since temperatures are lower on
heating plants which increases the lifespan of the sealing gland on the stem.
A filter must be installed upstream of the valve to increase functional safety.
Mounting
It is easy to assemble the valve and actuator; it can be done at the construction site. No
special tools or settings required.
Valve VVG44.. / VXG44.. is supplied with Mounting instructions M4364 (4 319 9564 0).
