2 Needle valve, stainless steel, model NA-, NA-Z, NA-ZZ escription Stainless steel needle valves are used to vary the flow cross section, thus regulating the flow volume. The flow is regulated by a cone-shaped valve that is moved by means of a spindle away from or toward the valve seat. The amount of flow change is determined by the size of the resulting angular gap between the cone and seat. The rate of flow change is determined by how much the valve spindle is turned as well as the pitch of the valve spindle thread. aterials Body stainless steel.457 Upper part stainless steel.457 Spindle stainless steel.457 land packing PTFE land stainless steel.457 Union nut stainless steel.430 and wheel molded resin esign two-part screwed body, with screwed-on upper part Connections /8 to /4 (IN ISO 228/) female thread, male thread, female and male thread /8 NPT to NPT female thread Temperature range -20 C to +20 C Nominal pressure PN 2 Female thread Female thread NPT Female/male thread ale thread N N NPT N N t t I I imensions and ordering details (example: NA-ZR 06) NPT Female/male thread thread Female thread ale thread NPT thread Female thread N 2 t l k v- value m 3 /h Weight kg /8 /4 /8-27 NPT /4-8 NPT -8 NPT -4 NPT -4 NPT -.5 NPT NA-ZR 06 NA-ZR 08 NA-ZR 0 NA-ZR 5 NA-ZR 20 NA-ZR 25 NA-R 06 NA-R 08 NA-R 0 NA-R 5 NA-R 20 NA-R 25 NA-ZZR 06 NA-ZZR 08 NA-ZZR 0 NA-ZZR 5 NA-ZZR 20 NA-ZZR 25 NA-N 06 NA-N 08 NA-N 0 NA-N 5 NA-N 20 NA-N /4 - NA-ZR 32 NA-R 32 NA-ZZR =-thread; 2 = NPT-thread 56

3 Needle valve,, model NA-AC escription KOBO NA-AC -needle valves allow economical regulation of the flow volume of liquids and gases. The amount of flow change is determined by the size of the resulting angular gap between the cone and seat. The flow is regulated by a cone-shaped valve that is moved by means of a spindle away from or toward the valve seat. The rate of flow change is determined by how much the valve spindle is turned as well as the pitch of the valve spindle thread. aterials Body CuZn 39Pb3F37 Bonnet (s 58) Spindle (s 58) Packing bottom-ring (s 58) Spindle seal /8 to = NBR to 2 = PTFE land nut (s 58) and wheel plastic esign two-part screwed body, with screwed-on upper part Connections female thread /8 to 2 (as per IN 259) Temperature range max. +00 C Nominal pressure PN 00 NA-AC Ø imensions and ordering details (example: NA-ACR 06) k V -value m 3 /h /8 /4 /4 NA-ACR 06 NA-ACR 08 NA-ACR 0 NA-ACR 5 NA-ACR 20 NA-ACR 25 NA-ACR NA-ACR NA-ACR
