DZR BALL VALVE

These are a robust, dezincification resistant ball valve that is particularly suitable for those
installations where high aggressive water causes zinc leaching in the standard brass alloys
and weakens the material molecular structure.

 

Features:

  • Dezincification resistant materials
  • Blow-out proof stem
  • Full bore
  • Very fast opening/closing in case of emergency
  • No maintenance - equipped with wrapping seats ensuring long life cycles
  • Antifriction ring forms the first automatic sealing at high pressure
  • Two self-adjusting cone-shaped seals, with Teflon sliding for second sealing at low pressure
  • 1 ‘O’ ring in EPDM for sealing at low pressure and vacuum
  • All valves are tested according to a strict procedure covering severe inspections 

    •  

    Suitable for:
  • An inlet for cooling engines
  • Generators
  • Air conditioning
  • Refrigeration units
  • Deck drain outlets
  • Exhaust outlets
  • Seawater inlets for toilets
  • Seawater outlets for toilets
