Dynamic balancing valves DN 15 - 32

• FUNCTION
• Flow and differential pressure control
• - Flow is set by the means of the baffle ring
• - Max. differential pressure i set by the
  means of
• an allen key
• Differential pressure control
• - Measured through the callibary
• - Minimising the differental pressure across
  the
• heating system or unit
• Locking nut
• - Secures the setting
• Shut off handle
• - Quater turn shut off of the risers

BALLOREX
Dynamic balancing valves DN 15 - 32

• BALLOREX QP M
• For two-pipe system
• QP always installed in the flow
• QP always connected to BALLOREX M by
• the means of the capillary
• When using BALLOREX Flowmeter, 5 x DN
• straight pipe is required to BALLOREX M
• Max. working pressure 10 bar
• Max. differential pressure 2 bar
• Max. water temperature 120 C0

• BALLOREX Q
• Controls the water flow between
• individual risers
• For use in one-pipe heating systems
• Can be mounted in the flow or in the
• return
• Secures correct distribution of water flow

BALLOREX
Dynamic balancing valves DN 15 - 32
Example Required Qmsx 0,125 l/s The spring
for the differential pressure (scale value) must
be set lowest possible e.g. position 2 (reduces
the pressure drop over the valve) At the
intersection between the graph position 2 and the
wanted water flow, the graph is followed to
reading of baffle position III

• BENEFITS
• Regardsless of pressure changes in the
• system
• (Keeps the set flow)
• Range 10-40 kPa
• Both for one and two-pipe heating systems
• Both flow and differential pressure control
• Measuring during setting
• BALLOREX Q can be installed both in the
• flow and the return line
