Description

This DZR Ball Valve 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
• 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

Suitable for:
