Actuators from Gruner –
Product range overview.When a suitable alternative is needed ...
High-quality actuators, from classic to customized.
The Slinky was invented in 1945 by Richard James. It conveys the full fascination
of physics – and simultaneously symbolizes pure flexibility. This symbolism is
reflected in the core values of Gruner AG. The actuators represent cost efficiency
and the greatest possible flexibility in building management. Here they cover all
requirements – from classic to air-volume control, and from very speedy actuators
to small spindle drives.
Typical applications:
• For motorized control of dampers, ball and butterfl y valves
•   Mixed air and shut-off damper control for primary HVAC
air-handling and zone units
• For controlling central and peripheral ventilation systems
• For smoke and waste gas dampers
•   Motorvalve for drinking, cooling, tap water, condense water,
air (f.ex. as zone valve)
• All actuators correspond to the DIN-VDE-standards
and CE-directivesDamper actuators HVAC.

Cost-effective alternatives with
characterised control valves.
Gruner control valves feature a parabolic port which
is a permanent part of the ball. The parabolic port
provides a wide range of k
vs
 choices while maintaining equal percentage fl ow in 2-way valves. In 3-way
valves a true linear heat transfer is accomplished. The
design features also a bypass k
vs
 not exceeding 80%
of the straight through k
vs
. This keeps always enough
pressure to control and saves pumping expenses.
• Nominal widths from DN 15 to DN 50
•  k
vs
 values from 0.38 to 310 m3
