RED-ROC PINCH VALVE

                                                   EDART INTRODUCES THEIR RED-ROC PINCH VALVE After extensive and successful site trials, South African based slurry valve manufacturer eDart Slurry Valves has introduced their Red-Roc range of pinch valves to the market. Designed specifically for tough slurries, dry & wet abrasives and corrosive chemical applications, their 100% full bore design is identical to a rubber lined pipe when fully open – eliminating the risk of slurry build up and contamination of mechanical working parts. The valves have a shortened face to face dimension similar to that of a diaphragm valve, and feature highly visible position indicators as standard. Feedback

The importance of good level control on flotation concentrators

“The link between level control and profitability on a flotation concentrator is often under-estimated or even overlooked, and yet accurate control measurement is the key to increased lifespan for plant and plant equipment, thereby increasing its operational profitability,” said Richard Rule, director of eDart Slurry Valves, based in Jet Park, Johannesburg. The purpose of a flotation concentrator is to recover the most amount of valuable mineral to the concentrate, whilst at the same time keeping the quantity of concentrate down to a minimum, which enables the highest recovery of valuable mineral at the desired grade to be achieved. This is

HYDROCORE’S MINE WATER PRESSURE REDUCING VALVES OFFER REDUCED DOWNTIME

The Hydrocore™ range of mine water pressure reducing valves offered by Dual Valves Australasia* feature a single moving part that is easily accessible for maintenance with the valve in the installed position. The valves are designed to handle a maximum inlet pressure of 250 bar (25 MPa) and are ideal for pressure reduction in underground mining applications. “Hydrocore™ pressure reducing  valves are designed to offer greatly reduced maintenance downtime, minimal operating costs and maximum system flexibility, and the simple design makes troubleshooting and repairs significantly easier compared with competing products” says Dual Valves’ Justin Mirto. He explains that, by removing

DUAL VALVES AUSTRALASIA OFFERS HYDROCORE™ U-CONE PIPE COUPLINGS

DUAL VALVES AUSTRALASIA OFFERS HYDROCORE™ U-CONE PIPE COUPLINGS – DESIGNED FOR SPECIFICALLY FOR HIGH PRESSURE MINING PIPELINES The Hydrocore™ U-Cone coupling offers mine engineers a simple and economical alternative to traditional flanges for use on high pressure pipe systems. Pipes are joined simply by bringing the ends of the pipe with welded hubs together after inserting the seal, fitting the clamp set over the adjoining hubs and tightening the clamp bolts. The external tapers on the hubs provide alignment while the clamp set pulls the hubs together, forming a simple but effective seal which comparable to similar rated conventional flange

EDART’S COARSE SAMPLER FOR MINING AND MINERAL PROCESSING APPLICATIONS

The eDart coarse sampler is used to provide samples of slurry from cyclone feed lines, tails lines and other mineral processing areas. It is pneumatically operated, stroking the sampler head into the process line or sampling chamber to trap a fixed volume of process slurry, and then retracting fully to allow the sample to discharge at atmospheric pressure through the outlet or dropping directly into a container. It is a robust poppet sampler specifically designed for the mining industry’s coarse and abrasive slurries, handling solids of up to 12mm present in the slurry. Meets composite or shift sampler requirements. The

DUAL’S HIGH PRESSURE KNIFE GATE VALVE SLEEVES REPLACE OEM SLEEVES AFTER EXTENSIVE SITE TRIALS

In another win for DUAL Valves Australasia, a West Australian alumina refinery has recently replaced a number of their 21 Bar rated OEM push-through style knife gate valve sleeves with sleeves from DUAL’s High Pressure knife gate valves – after reporting a tenfold increase in lifespan to date when using DUAL  sleeves in comprehensive site trials. “We were advised that their 21 Bar rated OEM knife gate valves were consistently failing after only four weeks in operation in the worst reported applications. A decision was taken by the refinery team to extensively trial a number of their knife gate valves

DUAL VALVES PARTNERS WITH HYDROMINE AND INTRODUCES THE HYDROCORE/NGD RANGE TO AUSTRALIA

Mine water control valves rated to 25MPa maximum pressure: Mine water pump discharge valve Mine water safety shutdown valve – a general safety valve, the mine water safety shutdown valve is activated by an analogue switch, and does not require an external actuator being powered by the line fluid pressure Energy dissipater – tailor made, often used together with the shock prevention valve fitted immediately after the mine water pump discharge valve on high pressure vertical or inclined systems. The energy dissipater is used in open end applications and designed to reduce upstream pressure to a set downstream pressure at
