9 COMBINED AIR RELEASE VALVES No. 9 No. 9 Design features This arrangement eliminates expensive valve chambers The stand pipe protects the automatic air valve Air valve for releasing air only: (with air inflow stop) on request (see over page illu. ) An automatic shut-off valve enables the equipment to be easily removed for inspection and reinstalled under pressure The materials used for the air release valve guarantee absolute corrosion resistance Excess water is drained away through an DN ½" ISO-pipe-fitting For below-ground installation a surface box with minimum opening of 00 mm diameter is required. Gravel backfilling should be used to prevent rain water from accumulating in the surface box (see Illu. page N 5/) The air release valve can be shortened by 0 mm by cutting the standpipe 5 and extension pipe at the red marks Valve only for air release: on request (minimum pressure of 0, bar needed) Material Technical features Order No. Standpipe made of stainless steel Air release valve made of POM and brass Working pressure bar Max. air release capacity:, m/min 50 Inlet flange: DN 50 or DN 0 sized and drilled according to EN 9- PN 1 9 PN 1 PN 1 0 Suitable accessories 50 Surface box No R 1½" Flushing stand pipe including shut-off valve; Instead of the air valve assembly a stand pipe can be supplied for water main flushing and for general water discharge PN 0,1 PN 0 *L = 0 reducible Order No. 9 L 755, ,0 105, ,50 Installation depth DN Above ground Below-ground (Illu.1) (Illu.) 0,75 m 1,5 m 0,75 m 1,5 m 0,75 m 1,5 m 0,75 m 1,5 m 1,5 m 1,5 m 1,5 m 1,5 m Minimum length = 50 Maximum length = 500 L* ,0,5,5 7,0 0,0 1,0,0 5,5 0,0,0,0,0 0,0,0 PN 5 on request Application example L = Total length of the combined air release valve Tel.: + (0) Fax: + (0) hawle@hawle.at - Edition N 5/1
