Mining is one of the most punishing environments for industrial equipment. Valves in mining applications must contend with abrasive slurries, corrosive chemicals, high pressures, and constant cycling. Standard valve designs wear out quickly, causing leaks, unplanned downtime, and costly replacements.
That’s why mining operations demand valves engineered with superior erosion resistance, to keep production moving in the harshest conditions.
The Erosion Challenge in Mining
- Abrasive Slurries: Ore, sand, and rock particles erode soft-seated and unprotected valves.
- Corrosive Chemicals: Processing fluids accelerate wear when combined with abrasive particles.
- High Cycling Rates: Repeated opening/closing stresses sealing surfaces.
- Downtime Costs: A failed valve can halt operations, costing millions per incident.
How Vestra Valves Solve the Problem
- Chromium Carbide Coatings
- Vestra applies rocket-applied Chromium Carbide coatings to balls and seats.
- Industry-leading hardness resists erosion, corrosion, and thermal shock.
- Mate-Lapped Seating Surfaces
- Precision-polished sealing surfaces ensure 100% contact for tight shutoff, even after wear cycles.
- Precision-polished sealing surfaces ensure 100% contact for tight shutoff, even after wear cycles.
- Pressure-Assisted Seating + Belleville Springs
- Maintain zero-leakage performance under fluctuating pressures common in slurry lines.
- Maintain zero-leakage performance under fluctuating pressures common in slurry lines.
- High-Performance Alloys
- Options like 410SS, F22, F91, and Inconel 718 extend service life in abrasive and corrosive conditions.
- Options like 410SS, F22, F91, and Inconel 718 extend service life in abrasive and corrosive conditions.
- In-Line Repairability
- Split-body design allows full replacement of worn components without cutting valves out of the line.
- Reduces downtime and OPEX for mining operators.
Why It Matters for Mining Operations
– Longer valve life in abrasive slurry service
– Reduced unplanned shutdowns and maintenance costs
– Improved safety by preventing leaks in high-pressure systems
– Lower total cost of ownership with repairable internals
The Vestra Advantage
Mining operations can’t afford frequent valve failures. Vestra’s combination of Chromium Carbide–protected sealing surfaces, mate-lapped shutoff, and in-line repairability gives operators confidence that their valves can withstand the toughest mining environments, day after day, cycle after cycle.
