This applies to when the metering station is used in a stand-alone application or close coupled to a double regulating valve. The pressure losses for the ART 26 double regulating valves are given on the individual flow charts along with the corresponding Kv values at the various positions open. Valve Features • The ART 26 & ART 27 DZR Commissioning Set is used for balancing the flow in heating, cooling and domestic water systems. • The ART 26 & ART 27 DZR Commissioning Set has a flow accuracy of +/- 5% flow accuracy. • The ART 26 & ART 27 DZR Commissioning Set is fitted with 2 test points. • Digital scale with lock function. • Made of “DZR” (Dezincification Resistant) brass. • This article is made in compliance with the quality management requirements of ISO 9001 standard. • All articles are tested in accordance with the EN 12266-1 standard. • It can be used in a wide variety of sectors: heating, air conditioning, water, sanitary systems and generally with any non-corrosive liquid.

Page 5: Regulating
Flushing Control valves are sized to give good control over the system water and have therefore been designed with small, convoluted flow paths. These water ways may not allow adequate water velocities needed for flushing the system during the pre-commissioning stages of water treatment, even when fully open. In line with BSRIA BG29 recommendations, suitable consideration needs to be made as to how the removal of system debris can be achieved during the system flushing process. Regulating • To close the valve rotate the handle clockwise until it stops. Using the data reported in the attached diagrams, the flow can be regulated by rotating the handle counter-clockwise until the required flow rate is reached. • This flow rate can be measured using a differential manometer. • This interfaces with the balancing valve through two sensors inserted in the binder points (Kvs) placed before and after the valve’s gauged diaphragm. • The main scale with values from 0 to 8 on the handle, indicates the turns for opening the obturator, while the second circular scale from 0 to 9 records the tenths of one turn. • The position of the handle at the required flow rate can be memorized using a 6 mm Allen Key.
