Overview
We are the Australasian agent for 3 specialist manufacturers of mining slurry valves, couplings, slurry poppet samplers and associated equipment:
1)The DUAL range of slurry valves - ball checks, isolation swing gate and rotary disc valves, air release vacuum breakers and pinch valves among others.
2) eDart range of internal/external dart valves and process control slurry poppet style samplers
3) Hydromine Projects Intl. range of high pressure underground water control valves and pressure reducing stations
Products and Services
Slurry ball check valve: The DUAL combination ball check and lockout isolation valve - a unique slurry ball check valve that offers a hand wheel operated or actuated lock out facility. We have supplied up to Class 900# into mining for de-watering application in Australia.
Slurry Ball check valve: The Dual Dashley valve - a double ball check slurry changeover valve used on cyclone feed pump sets that offers positive isolation onto each inlet leg from the pumps independently from the other leg. Units manufactured up to Class 300#.
Slurry ball check valve: The Dual DDNRV valve - a single ball changeover valve used on cyclone feed pump sets to isolate the inlet leg from the standby pump. Units manufactured up to Class 300#.
Slurry ball check valve: The Dual FreeFlow valve. Heavy duty slurry ball check valve with replaceable seat. Class 900# maximum.
Slurry ball check valve: Dual SlimLine valve. Slurry ball check valve with integral seat - usually rubber lined internally. Class 600# maximum.
Slurry over protection valve: Dual pump protection valve. Spring loaded urethane ball system providing over pressure relief.
Slurry isolation valve: The Dual Rotary Disc valve. Isolation rotating gate valve for heavy slurry applications. Full Class 600# rated maximum.
Slurry isolation valve: The Dual pivot gate valve. Similar to push-through design of knife gate valve with replaceable rubber sleeves, but this features the gate swinging in sideways to dislodge slurry/scale build up at the bottom of the pipe when closing. Up to full Class 300# rating available.
Slurry air release/vacuum breaker valve: The DSARV Dual air valve/vacuum breaker - extensively proven and robust high pressure slurry ARV used in tailings lines worldwide. Applied in units up to Class 900#.
Slurry pinch valves from DUAL for both isolation and flow control applications.
Slurry samplers: eDart Poppet and Thief style process control samplers used for cumulative sampling on slurry with particles up to 12mm (eg on cyclone feed circuits). Recirculating offset centre pipe units are offered for larger diameter pipe installations.
Dart valves: eDart range of standardized internal drop-in style and extended depth dart valves for applications in flotation circuits, splitter boxes, conditioning tank etc. as well as external dart valve designs for use on tank outlets and inline applications with both single and double valve versions available for extremely accurate flow and level control. eDart offer world best practice in design and application of dart valves.
Pinch valves from eDart for both isolation as well as control applications.
Slurry isolation: C-Tech Metal seated knifegate valve rated PN16.
Pneumatic actuators: eDart manufacture and design their own range of pneumatic double acting cylinders for application in the mining industry.
Back Pressure Pipes: eDart assess, design and manufacture back pressure pipes to solve excessive pressure drop issues across the final outlet valve often experienced in flotation circuits. They use their extensive Flo/EFD capabilities coupled with extensive experience to provide these solutions.
High pressure underground water control valves: Hydromine Projects Intl. offer a standard range of pressure reduction valves, non-return valves, excess flow shutdown valves and back pressure sustaining valves typically applied in underground fire and process water reticulation applications. Rated up to 250 Bar.
High pressure underground isolation valves: Hydromine Projects Intl. offer a standard range of high pressure isolation valves specifically designed for underground fire and process water isolation. Rated up to 250 Bar.
High pressure pipe couplings: Hydromine Projects Intl. offer a range of welded hub and collar designs for use in underground piping rated up to 250 bar.
