Dual Products International has been manufacturing slurry valves for over 20 years, and is one of the Worlds leading manufacturers of abrasion resistant valves. Our commitment to providing a total solution to our valued customers has led us to introduce new abrasion resistant products including Dashley Double Ball Check Valve,Slurry Air Release Valves,and Rotary Disc Gate Slurry Valves.

The Rotary Disc Slurry Valve is a new and unique rotating gate valve designed specifically for heavy abrasive and corrosive slurries, water etc. The Dual Rotary Disc Valves' patented design allows the valve to cycle in heavy slurries without sticking. There are two types: rising and non rising spindle, and high or low pressure valves. Dual Products produces valves for the mining, sands, steel, power, chemical and paper industries worldwide and has exported valves to more than 25 countries.

 Our complete range includes :

•   Dual Valve – the unique slurry ball check valve with lockout facility. Only the
    DUAL Valve offers this safety feature. Ideal as a mine dewatering valve if
    suspended solids are significant, or as a slurry ball check valve.

•  Dual Free Flow Valve – slurry ball check valve with replaceable seat

•  Dual Slimline Valve – slurry ball check valve with integral body seat Also
   see the Dual FloStop valve for clearer fluid application

•   Dual Slurry Air Release Valve/Vacuum Breaker – ideal for tailings lines
    and dirty water vacuum breaker use

•  Slurry vacuum breaker – use Dual Slurry Air Release Valve/
    Vacuum Breaker

•  Slurry non return valve – choice of Dual SlimlIne Valve or Dual Free Flow Valve

• Dual Dashley Double Ball Check Valve – cyclone feed changeover double ball valve featuring replaceable elastomer seats

•  Dual Double Non Return Valve DDNRV – cyclone feed changeover single ball valve featuring replaceable elastomer seats

•  Dual Rotary Disc Valve – used as tailings isolation valve or general slurry isolation valve, the Dual Rotary Disc valve can be
   urethane lined for high wear applications

•   Dual Slurry Knife Gate Valve – heavy duty replaceable sleeve design in flanged, wafer and high pressure (25 Bar) options.

•  The Dual Slurry Knife Gate Valve is standard 10 Bar rated, and the Dual High Pressure Slurry Knife Gate Valve is 25 bar rated
   as standard. These units are also used as a general slurry isolation valve as well as a tailings isolation valve

•  Tailings changeover valve – the Dual Double Non Return Valve DDNRV can be operated lying on its side as long as the
    backpressure required is adequate – just ask us how

•  Cyclone feed changeover double ball valve – the Dual Dashley Double Ball Check Valve can also be supplied with hand
   wheel or actuated lockout facility to keep the ball on the seat – a unique and significant health and safety feature

•  Dual Flo-Stop Valve – a mine dewatering valve used on clearer fluids, especially suited to high pressure mine dewatering
   valve applications.
