ASV-I is a partner valve to be used together with the automatic balancing valves ASV-PV/P to control differential pressure in the risers where the radiator valves have no presetting facilities. It is a combined adjustment and shut-off valve designed for installation in the flow pipe. It incorporates flow limitation so that it can be set for required maximum flow in the riser. ASV-I is supplied with rectus measuring nipples so that flow in the pipe can be measured. The valve (DN 15-40) is packaged in styropore (EPS) which can be used for insulation at temperatures up to 80 °C. An insulation cap is available as an accessory for insulation at higher temperatures (up to 120 °C).
