Radiator valves featuring integrated differential pressure control for

2-pipe heating systems, fan coils and chilled ceiling systems

• Automatic flow limitation under all operating conditions

• Straightforward design of plant with no need for safety margins

• Thanks to MCV no hydraulic balancing within the zone required

• No additional line balancing valves required

• No noise problems

• Integrated presetting of k

-values

• DIN DN 10 and DN 15

• Valve bodies made of brass, mat nickel-plated

• Internally and externally threaded (Rp/R) conforming to ISO 7-1

• Can be combined with RTN.. thermostatic, STA..3.. electrothermal and SSA..

electromotoric actuators

Use

The MiniCombiValves are designed for use in 2-pipe heating systems, fan coil and

chilled ceiling systems to provide individual room control and limitation.

The MiniCombiValves with integrated differential pressure control ensure that the

amount of heat emitted by the radiator is well defined, irrespective of operating

conditions. For this reason, line balancing valves normally used for hydraulic balancing

are no longer required.

Due to their integrated differential pressure control, these valves are extremely well

suited for new houses and buildings, or for upgrading plants where hydraulic problems

have occurred. They are basically recommended in all rooms, especially where heat

gains or different temperature levels occur.

Engineering notes The MiniCombiValves allow preadjustment of the required volumetric flow V . This preadjustment is made by limiting the valve's stroke. With the MiniCombiValve, the adjusted value represents the maximum flow rate because the integrated pressure controller maintains the volumetric flow at a constant level, even if the differential pressure varies between 0.1 and 2 bar.

Maintenance The MiniCombiValves require no maintenance. Repair If the stem sealing gland leaks, the stroke limiter can be replaced by valve insert AV100-VP1. Otherwise the valves cannot be repaired, they have to be replaced as complete units. Disposal Do not dispose of the device as household waste. Disposal • Special handling of individual components may be mandated by law or make ecological sense. • Observe all local and currently applicable laws and regulations.
