BALLOREX® Venturi
COMMISSIONING VALVES DN 65-300

BALLOREX® Venturi             introducing unique benefits

  • Signal range (10-60 kPa)
  • Built in up- and downstream length
  • Gear box double regulation function
  • Unique secure Memory Stop
  • Accuracy of +/- 3%
 Applications

BALLOREX® Venturi has been developed on the basis of a proven technology resulting in a unique solution for the modern heating and chillid water systems.

The concepts incorporated into the BALLOREX® Venturi provide significant benefits for consultants, contractors and commissioning engineers enabling systems to be designed, installed and handed over without any technical complications.   

The Heart of BALLOREX® Venturi is the fixed orifice cartridge, which is integrated into all BALLOREX® Venturi commissioning stations.

To improve the installation of BALLOREX® Venturi 2 new concepts have been introduced:

The BALLOREX® Venturi can be installed in any orientation even with the pressure tapping points positioned downwards. 

No additional straight pipe lengths are required before or after the BALLOREX® Venturi valves, as these are incorporated in the valve body. 
Specification

Both the Venturi commissioning station (FODRV) and the double regulating valve (DRV) incorporate a characterised regulating butterfly valve with fixed liner. All steel valves in the BALLOREX® Venturi range are operated by means of a manual gear with memory stop, which is used to allow operation only between set point and closed position. This double regulating feature allow the disc setting to be locked in position (using an Allen Key) and will return to the exact set position after isolation in a gear box with memory stop.

FODRV: The flow rate can be measured using a fixed Venturi Orifice steel pipe with test points. The commissioning station is suitable for mounting in any orientation with the Venturi test points positioned between 8 and 4 o'clock.

DRV: It is not possible to measure the flow through the valve. The butterfly valve is suitable for mounting in any direction.

Standard pattern

The up and down streams length is not included. The upstream straight pipe shall be 5 x DN. However when the valve is installed within close proximity to a pump the upstream straight pipe shall be 10 x DN.

Extended pattern

The assembly shall incorporate the up and down stream lengths required for highest accuracy in flow measurement, except when installed within close proximity to a pump. 5 x DN straight pipe is allowed upstream.
