DZR Ball Valve 1 1/4″ BSP

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. 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 entire production Suitable for: • Inlet for cooling engines • Generators • Air conditioning • Refrigeration units • Deck drain outlets • Exhaust outlets • Seawater inlets for toilets • Seawater outlets for toilets Temperature Limits: Fluids: -15°C to 120°C Pressure Limits: Fluids: 25 Bar Thread: Female Parallel Thread ISO 228/1 Materials: Body & Threaded End: DZR Copper alloy CW602N (UNI EN 12165) Gland: DZR Copper alloy CW614N (UNI EN 12164) Stem: DZR Copper alloy CW602N (UNI EN 12164) Ball: Chrome Plated DZR Copper alloy CW602N (UNI EN 12164) Seals: Pure PTFE (Teflon) O-ring: EPDM Lever: Zinc plated steel, PVC coated Grip Fixing Nut: Zinc plated steel
