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.

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


entire production
