NK valve
ZS slice
  • Non-slam closure
  • Low weight
  • Very Short face-to-face length
  • 1" - 10" (DN 25 - DN 250)
  • Low pressure loss
  • Maintenance free
  • Metal sealing
  • Up to PN 400 (ANSI 2500)

With a shorter face-to-face (wafer type) than the ZB and where pressure loss across the valve is not such a significant consideration,

the ZS is installed where space and weight is at a premium. This type is only available on special request.
