Engineering
We recommend installing the ball valve with spring return since temperatures are lower on
heating plants which increases the lifespan of the sealing gland on the stem.
Ensure there is no cavitation (see section Technical design [➙ 2]).
A filter must be installed upstream of the ball valve to increase functional safety.
We recommend using temperature adapter ALJ100 in locations exposed to condensation to
protect the actuator. Lubricate the adapter axle with silicon grease at medium temperatures
≤ 0 °C.

Permissible media
Using the ball valve in combination with potassium formate-based media, such as Hycool or
Temper, can result in leakage over the stem to the outside. The reason is the high level of
penetration at low surface tension of media based on potassium formate.
Siemens rejects any and all liability for damages or consequential damages resulting from
the use of this media in combination with our ball valves.
Mounting
It is easy to assemble the ball valve and rotary actuator; it can be done at the construction
site. No special tools or settings required.
Ball valve VAG60.. / VBG60.. is supplied together with mounting instructions M4214 (74 319
