Engineered with hardened internal trims, structural forging density, and bidirectional tight shut-off to withstand abrasive mine tailings and autoclave extraction lines.
The global mining industry is undergoing a monumental technological shift. As high-grade ore reserves deplete, mineral processing facilities must process higher volumes of lower-grade ores, leading to harsher processing conditions characterized by higher slurry densities, elevated corrosive chemical concentrations, and intensified continuous operating regimes. In this challenging landscape, the forged ball valve for mining and mineral processing has established itself as an indispensable mechanical asset.
Unlike conventional casting valves, which frequently suffer from subsurface porosity, pinholes, micro-cracking, and structural grain irregularities, forged steel valves deliver uniform grain flow, maximized mechanical density, and exceptional tensile resistance. In heavy hydrometallurgical operations, High-Pressure Acid Leach (HPAL) systems, and long-distance hydro-transport slurry pipelines, forged ball valves provide zero-leakage isolation under cyclic shock loads, abrasive particle impingement, and thermal cycling.
Forging refines internal crystal orientation, eliminating casting defects and providing ultimate impact toughness against hydraulic water hammer and severe pressure surges in slurry transport.
Integrated with specialized metal-to-metal seating technologies, Tungsten Carbide (WC-Co-Cr), and Chromium Carbide coatings to resist extreme solid particle scour.
Available in high-nickel alloys, Duplex/Super Duplex stainless steels (F51/F53/F55), Titanium, and Hastelloy grades tailored for aggressive acid leach recovery lines.
From primary ore extraction to refining and tailings reclamation, each mineral circuit requires tailored valve configurations.
Operates at Class 900 to Class 2500 under 250°C+ sulfuric acid media in Nickel, Cobalt, and Gold pressure oxidation plants, requiring forged titanium/alloy trims.
Iron ore and copper concentrate high-velocity slurry lines demand full-port forged trunnion designs that minimize turbulent eddy formation and prevent localized cavitation wear.
High-density solids discharge creates chronic scaling and packing zone blockage. Scraper-type seat designs keep sealing faces cleared of mineral scale.
Pneumatic and paste backfill systems require bidirectional zero-leakage Double Block & Bleed isolation to protect equipment during high-pressure maintenance cycles.
With over 30 years of manufacturing experience, SLVCN is a professional designer and manufacturer of high-performance forged steel ball valves for critical industrial applications. We specialize in extreme working conditions including high pressure, high temperature, and cryogenic environments, providing safe and reliable flow control solutions for global industrial projects where operational reliability is non-negotiable.
Our core product range covers forged trunnion-mounted and floating ball valves, top-entry and side-entry ball valves, fully welded ball valves, metal seated ball valves, cryogenic ball valves, high-pressure ball valves up to Class 2500 (PN420) and customized higher pressure ratings, as well as high-temperature service valves. Compared with conventional cast valves, SLVCN forged valves feature higher material density, superior mechanical strength, improved resistance to pressure fluctuations and thermal shock, and significantly longer service life under severe service conditions.
Safety and reliability are embedded in every design. Our forged ball valves are equipped with Double Block and Bleed (DBB) structures, anti-blowout stems, fire-safe designs in accordance with API 607 / API 6FA, anti-static devices, emergency sealing systems, and pressure-balanced seating structures suitable for high differential pressure operation.
Valves can be designed with Single Piston Effect (SPE) or Double Piston Effect (DPE) seat configurations based on application requirements. For sour service environments and corrosive tailing acids, materials and sealing systems strictly comply with NACE MR0175 / ISO 15156 requirements.
Designed for High Pressure, High Temperature, and Cryogenic Applications, SLVCN valves are widely used in long-distance oil & gas transmission pipelines, mining slurry lines, LNG storage and regasification terminals, offshore platforms, power plants, refineries, compressor stations, and high-pressure chemical processing units. Whether handling flammable media, corrosive fluids, sour service media (H₂S), ultra-low temperatures, or extreme differential pressures, our valves ensure stable operation, bubble-tight shut-off, and maximum system safety.
To ensure consistent quality, each valve undergoes a complete series of inspections and performance tests in accordance with API 6D, API 598, and ISO 5208, including shell test, seat leakage test (Rate A / zero visible leakage), fire-safe test, cryogenic test, operational torque test, dimensional inspection, and PMI material verification. SLVCN operates dedicated cryogenic testing facilities to validate valve performance at ultra-low temperatures down to −196°C.
SLVCN is certified to ISO 9001, CE, and API standards, and our products comply with API 6D, ASME B16.34, DIN, ANSI, and JIS specifications. We provide extensive customization capabilities covering sizes from 1/2” to 36”, full bore or reduced bore, special materials including A105, LF2, F11, F22, F51, Inconel, various soft and metal seat designs, and intelligent actuation with pneumatic, electric, and gear operators.
Today, SLVCN serves customers in more than 100 countries and regions, supplying valves to EPC contractors, engineering companies, and end users across Europe, the Middle East, Southeast Asia, and the Americas. Backed by strong engineering expertise, advanced manufacturing, and rigorous quality control, SLVCN is committed to delivering safe, durable, and truly engineered valve solutions for the world’s most demanding industrial projects.
