  • Kvs 10 m³/h; ps 1600 kPa.
  • Medium: water or water with max. 50% vol. glycol.
  • Medium temperature: -10...100°C [14...212°F].
  • Differential pressure: ∆pmax 200 kPa; closing pressure: 1400 kPa.
  • Flow characteristic: equal-percentage; leakage: bubble-tight, leakage class A.
  • Nickel-plated brass body; stainless steel closing element and stem.
