Notes
Security
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 ball valve in the return pipe, as the temperature is
● higher for application in cooling systems and
● lower for applications in heating systems,
which could extend the life of stem sealing gland.
Please ensure the flow is cavitation free (refer to Sizing [▶ 3]).
Please always install a strainer upstream of the valve to increase the valve's functional
safety.
Mounting
Both ball valve VAF41.. and rotary actuator GEB..1E, GIB..1E or GCA..1E can easily be
assembled on site. Normal tools and adjustment are required.
The valve is supplied with Mounting Instructions A6V11162533 (A5W90003152).
