Use
· For use in ventilation and air conditioning systems for water-side control of chilled
ceilings and terminal units in closed circuits, e.g. for induction units, fan coil units,
small re-heaters and small re-coolers.
- 2-pipe systems with 1 heat exchanger for heating and cooling
- 4-pipe systems with 2 separate heat exchangers for heating and cooling
· In closed-circuit zone heating systems, e.g. for:
- Separate floors in a building
- Apartments
- Individual rooms

1)
Preadjustment of flow rate: > 1.5 mm valve stroke.
If the valve travel is less than 1.5 mm, self-calibration is not possible and the valve with the actuator
remains blocked.
2)
Preadjustment of flow rate: > 0.5 mm valve stroke.
If the valve travel is less than 0.5 mm, self-calibration is not possible and the actuator generates an error
message.
Mechanical and technical design
The valves make possible flow rate preadjustments by limiting the stoke. A preadjusting
screw with reference numbers from 0 to 7 is located under the protective cover right by
the valve stem.
1 Gland with preadjusting ring
2 Valve insert
3 Fitting with O-ring
4 Valve plug with soft disk
5 All valves are supplied with a protective cover.
That cover facilitates shutoff when making the
plant pressure test and manual adjustments for
improvised plant
operation during the construction
