  • Light weight construction results in lower cost and simplified installation.
  • No extra pipe support needed when installed in plastic or GRP piping.
  • Disc in high engineered composite material provides excellent corrosion resistance.
  • All fasteners in stainless steel 316 as standard.
  • Bubble tight shut-off in both directions, in accordance with EN 12266-1 leakrate A.
  • Pressure range up to PN 16 at elevated temperature.
  • Valve can be used in high line velocity applications up to 12 m/sec.
  • Spindle and primary valve seals are not influenced by the flange bolting force or pipe flange type.
  • High Kv (Cv) value.
  • No need for flange gaskets.
  • Primary stem sealing exceeds the pressure rating of the valve and prevents leakage through the shaft area to atmosphere.
