Shield provides specialized abrasion‑resistant and high‑temperature valve solutions for mining, mineral processing, and metallurgy. Our valves ensure reliability and durability in demanding applications like slurry transport, tailings handling, smelting furnaces, and metal processing.
Hard‑Faced Alloys Up to Extreme Temperatures Slurry & Tailings Abrasion Resistant Wear‑Compensating Seals
Slurries containing ore particles, tailings, and concentrates are highly abrasive. Hard‑faced alloys, tungsten carbides, and engineered ceramics provide exceptional wear protection, extending valve service life significantly.
Mineral processing, smelting, and hydraulic roof support systems demand valves that reliably handle extreme pressures and temperatures. Our designs incorporate multi‑stage trims and high‑grade materials.
Valve failure can lead to catastrophic downtime, environmental incidents, or safety hazards. Our valves ensure bubble‑tight shut‑off for critical systems like mine dewatering, gas control, and hydraulic roof supports.
Abrasion and Erosion: Slurry pipelines rapidly degrade valve internals – requiring hard‑faced alloys or ceramics.
Corrosion: Highly acidic or alkaline solutions (leaching, refining) attack standard materials.
High Pressure and Temperature: Mineral processing, smelting, and roof supports need extreme‑duty valves.
Clogging and Scaling: Slurries with high solids content require anti‑clogging designs for easy maintenance.
Safety and Reliability: Critical systems demand zero‑leakage and fail‑safe operation.
Heavy‑Duty Slurry Valves: Full‑flow passages + wear‑resistant alloys for tailings and slurry transport.
Reliable Control Valves: Precise flow/pressure control for mineral processing, hydrometallurgy, and smelting.
Equipment‑Specific Valves: Valves compatible with mining machinery, shield tail grouting, and TBMs.
Engineering for Extreme Service: Rigorous application analysis ensures optimal material selection and performance.
Slurry Valves: Full‑bore, hardened alloy or stainless steel trim. Ideal for tailings pipelines, ore concentrate transport, and feed systems.
Dome Valves: Quarter‑turn with inflatable seal for abrasive media. Critical for pneumatic conveying of dry powders and bulk solids in smelters.
High‑Pressure Hydraulic Control Valves: Fast response, minimal internal leakage, multi‑stage for high flows. For longwall shield supports, roof bolters, heavy machinery.
Knife Gate Valves: Sharp gate for thick slurries, replaceable liner/seal. Isolation on thickener underflow, settling ponds, coarse slurry lines.
Specialized Support Equipment Valves: For shield tail grouting and safety protection systems on TBMs and hydraulic roof supports.
Advanced Materials: Super duplex stainless steels, tungsten carbides, engineered ceramics extend service life.
Smart Valve Systems: IoT sensors and actuators enable predictive maintenance, remote monitoring, and real‑time flow optimization.
Design Optimization: Multi‑stage valves achieve opening times as fast as 21 ms and flow rates over 200 L/min for hydraulic control.
Enhanced Sealing Technologies: Dynamic inflatable seals in dome valves provide excellent shut‑off in abrasive environments, operating reliably for over a million cycles.
Engineered for wear resistance, corrosion protection, and reliable shut‑off in harsh environments.
