DZR BALL VALVE
The ISIS is a robust, dezincification resistant ball valve that is particularly suitable for those
installations where high aggressive water causes causes zinc leaching in the standard brass alloys
and weakens the material molecular structure.
Dezincification resistant materials.
Blow-out proof stem.
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.
