MG = diaphragm size. Kv values determined acc. to IEC 534 standard, inlet pressure 6 bar, Äp 1 bar, PVC-U valve body and soft elastomer diaphragm. The Cv values in gal/min apply to US-gallons. The permissible operating pressure also depends on the temperature of the working medium, see page 141. Control function Code Normally closed (NC) 1 Normally open (NO) 2 Double acting (DA) 3 Diaphragm material Code NBR 2 FPM 4 EPDM 14 PTFE/EPDM PTFE laminated 52 For valve body dimensions see pages 44 - 47.
