Valve solutions designed for the most demanding mining environments
In the mining industry, installations are exposed to particularly harsh conditions: abrasive and viscous fluids, high pressures, the presence of solid particles, and the risk of solidification. These constraints can lead to premature equipment wear, blockages, and complex maintenance operations.
With its expertise in the design of tailor-made industrial valves, Guichon Valves Origin supports mining industry players with reliable, robust solutions adapted to the specific requirements of each installation.
From tank draining to the transportation of slurries and backfill pastes, our valves are designed to minimize erosion, prevent blockages, and ensure operational continuity, even under the most demanding conditions.
Our solutions for the mining industry:
Process batchTank bottom outlet valve Recommended valve type: 602N/M – Tank Bottom / Outlet Valve Piston type tank bottom outlet valves have revolutionized tailing batching plants by allowing end users to utilize the integral piston ram to break though solidification or sediment that as formed in the base of mixing tanks and digesters. No longer do plant operators need to unsafely “rod” back through outlet valves and drain valves to remove blocked outlet ports. These valves seal tightly also against the paste and tailings solids preventing the unwanted loss of process media and fluids |
Paste diverterBore line paste diverter valves Recommended valve type: 306N – Turning Piston Mining Diverter Valve This technology enables the diversion of paste or tailings flow upstream or downstream of paste processing systems. It can also be used in any high-pressure abrasive slurry system to divert flow from one pipeline to another without costly pipework disconnection. Depending on the position in which the valve is installed, it can easily be converted from a diverter valve to a switching valve simply by installing it in the opposite orientation. |
Paste dumpBore line paste dump valves Recommended valve type: 605N / 608N – Emergency Dump Paste Valve Paste system blockages resulting from solidification and segregation is a key area of frustration for mining companies operating paste delivery systems as they typically lead to lengthy downtime and expensive remedial works to clear the blockages. The design of this valve provides the ability to dump residual paste and flush fluids away from stope delivery point on demand or in an operational upset condition. This solution can significantly reduce maintenance costs by avoiding the need for complete line replacement, potentially saving thousands of dollars. As an emergency / safety device in pipe burst or over-pressurization situations you also need absolute confidence that the technology you chose will perform on demand and itself not become a point of blockage like alternative dump solutions currently on the market |

| Normal Operating Position: Close
Action when signal is given to perform dumping: Piston will move to crust breaking position for a moment to break and dislodge any solidified paste. Then piston will go down in the body allowing any accumulated paste or flushing fluids to get out of the dump port |
