To maintain cost-effective operation of pressure acid leaching, there is the ValvTechnologies’ severe service acid injection ball valve. A unique product, it was created and designed for the isolation and emergency shutdown of high-pressure acid leaching (HPAL) autoclave acid injection systems. This valve uses ceramic seats, coatings, and exotic metals to provide plant safety in the harshest of process conditions. Its operating benefits continue to be demonstrated every day in mining facilities throughout the world.
The acid injection valve product line is used in the mining industry for high-pressure acid leaching HPAL of nickel, using autoclave technology. The acid injection valve product is an invention of ValvTechnologies, in response to a need for a special application valve, as a result of a hazard and operability study which was carried out for the Bulong Nickel Project in 1997.
