DZR BALL VALVE

The ISIS is 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 on the
