Join us from May 9 to 12 at the “Mining Indaba” event !
Investing in African Mining Indaba is the worlds largest mining investment conference, dedicated to the capitalisation and development of mining in Africa.
VALCO GROUP purpose several custom-made valve solutions for Mining application :
Process batch, 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 through solidification or sediment that has 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.
Pump switch multiway valve
Primary purpose is for flow diversion / switching of paste or tailings slurry from one delivery pump and switch to a second delivery pump in high demand applications without the disconnection of pipework or interruption to the batching plant production.
Depending on the direction the valve is installed, it can easily be converted between a DIVERTER to a SWITCHING valve simply by installing in reverse.
Paste diverter, bore line paste diverter valve
Primary purpose is for flow diversion of paste or tailings in both above and below ground reticulation systems, but can also be used in any high-pressure abrasive slurry system to divert flow from one pipeline to another without costly and continuai pipework disconnection and reconnection to change diversion of flow. Depending on the direction the valve is installed, it can easily switch between a Diverter Valve to a Switching Valve simply by installing in reverse.
Paste Dump, bore line Paste Dump Valve
Paste system blockages resulting from solidification and segregation are 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.
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 durnp solutions currently on the market.
