User manual HONEYWELL R295H

[. . . ] R295H Mechanical disconnector hydraulic actuated GB type according to EN1717/ type 2 according to DIN1988 part 4 Product specification sheet Application Mechanical disconnectors of this type are suitable for the protection of drinking water systems as required by EN 1717 "The technical regulation of drinking water systems" and correspond to DIN1988 part 4 type 2 construction. [. . . ] When the outlet pressure drops due to water consumption, the differential pressure in the disconnector rises. If the differential pressure rises above 0. 5 bar, the hydraulic operator causes the control valve to changeover the mechanical disconnectors into the flow position. When the water consumption stops, the differential pressure decreases and the differential pressure transducer transmits a signal to the control valve, which then returns the disconnector to the normal shutoff position. A = With female threaded union connectors, differential pressure 0. 5 bar, self-adjusting Special Versions available on request Connection size Connection size Weight Dimensions Nominal flow rate at p = 0. 8 bar kvs-value value DIN/DVGW Approval No. R approx. kg mm L l H h T m3/h 1/2" 3/4" 1. 4 151 105 153 125 76 2. 2 2. 5 13. 0 1. 6 153 105 155 123 80 3. 1 3. 5 20. 9 1" 1. 8 159 105 155 123 80 11/4" 4. 3 216 150 232 155 93 11/2" 4. 9 228 160 231 159 93 12. 5 14. 0 20. 9 2" 5. 3 241 165 224 166 98 14. 3 16. 0 39. 0 3. 6 8. 9 4. 0 10. 0 39. 0 16. 8 NW - 6301 AT 2320 Accessories M07M Pressure gauge Subject to change without notice EN0H-1206GE23 R0206 Housing diameter 63 mm, rear connection thread G1/4".

However they can also be used for supplies to residential buildings within the scope of their specification.
