When the ore medium changes from a single mineral to a mixture of multiple metals such as gold, silver, copper, lead, zinc, and sulfur, ordinary valves often struggle to withstand the rapid wear and tear of high-hardness slurries.

Our KNFV-KF polyurethane knife gate valves, with their superior corrosion and wear resistance, have been successfully applied to multiple key operating points in a gold and silver polymetallic mine in Fujian Province. This mine involves the separation and transportation of various high-hardness metallic minerals such as copper, lead, zinc, and sulfur, placing extremely high demands on the valves' impact resistance and sealing performance.

From the high-pressure impact at the hydrocyclone feed inlet to the complex fluid at the tailings pump inlet; from the frequent opening and closing of the copper, lead, zinc, and sulfur concentrate pump inlets to the high-concentration underflow at the thickener underflow pump outlet—KNFV-KF valves are present throughout the entire production line.

King of Wear Resistance: Utilizes high-performance polyurethane material, offering excellent elasticity and high hardness, effectively resisting the cutting and abrasion of multi-metallic mineral particles.

Like-New Sealing: Maintains a zero-leakage seal even under frequent opening and closing conditions, eliminating leaks and spills.

Cost Reduction and Efficiency Improvement: Significantly reduces valve replacement frequency, helping mining customers achieve continuous and automated production.

Core Applications: Hydrocyclone feed, tailings conveying, inlet of various concentrate pumps, underflow discharge from thickeners.

Operating Conditions: High concentration, strong abrasion, multi-metal corrosion.

Customer Value: With its ultra-strong polyurethane lining resisting severe wear and its superior sealing ensuring process stability, DETORA is the trusted first choice for wear-resistant valves in the mining industry. For mining valves, choose DETORA!
