Lithium Service Valves

Falcon Valves and Flanges Pvt. Ltd. manufactures a specialized line of service valves designed specifically for high-consequence chemical environments, including Lithium service (often associated with Lithium Hydroxide or Lithium Brine processing).

Because lithium compounds—particularly in liquid or slurry form—can be highly abrasive, corrosive, and prone to crystallization, these valves are engineered for extreme durability and sealing integrity.

• Specialized Material Selection: To resist the chemical degradation caused by lithium salts and alkalis, Falcon utilizes high-grade materials such as Titanium Grade 2, Alloy 20, Hastelloy, Duplex/Super Duplex Stainless Steel, and Monel.

• Leak-Proof Sealing: Designed to prevent the escape of hazardous lithium-based fluids, these valves often feature enhanced gland packing and reinforced seat designs to maintain a tight shut-off.

• Anti-Crystallization Design: Many of these valves are designed with smooth internal flow paths to prevent "dead zones" where lithium salts might settle and crystallize, which could otherwise lead to valve jamming or seat damage.

• Standard Compliance: They are typically manufactured to meet international standards such as API 600, API 6D, API 607 (Fire Safe), and ISO 15848 (Fugitive Emissions).

• Lithium Mining & Extraction: Handling aggressive brines and acidic solutions during the leaching process.

• Battery Chemical Processing: Specifically for the production of Lithium Hydroxide and Lithium Carbonate.

• Refining: Used in the chemical treatment and purification stages where moisture-sensitive or corrosive lithium compounds are present.

Falcon Valves and Flanges Pvt. Ltd. provides specialized flow-control solutions for the lithium industry, focusing on the unique challenges of brine extraction and chemical refinement. Lithium service is particularly demanding because the media—often high-concentration brines or chemical slurries—is both highly corrosive and highly abrasive, with a tendency to crystallize and seize moving parts.

Below are the expanded technical and design details for these valves:

Standard stainless steel often fails in lithium brine service due to chloride-induced pitting. Falcon utilizes superior alloys to ensure longevity:

• Body & Gate/Ball: High-grade alloys like Hastelloy C276, Titanium (Grade 2 or 5), Super Duplex (SS 2507), and Alloy 20.

• Linings: For acidic slurries or leaching processes, valves may feature PFA/FEP linings or full body liners that protect the metal from direct contact with aggressive media.

Lithium salts (Lithium Carbonate/Hydroxide) readily precipitate out of solution, which can "freeze" a valve.

• Self-Cleaning Seats: In ball valves, the seat design often includes a "scraping" action to clear crystals from the ball surface during every cycle.

• Knife Gate Technology: For lithium slurries, Falcon provides Knife Gate Valves that can cut through thick media and solids. These often feature a "bottomless" or "through-conduit" design so that solids are pushed out rather than trapped in the seat pocket.

• Cavity Fillers: Ball valves can be fitted with PTFE cavity fillers to eliminate dead spaces where brine could settle and crystallize.

• Evaporation Pond Management: Handling raw, concentrated brine.

• Ion Exchange & Solvent Extraction: Control of purified lithium streams.
• Precipitation Tanks: Regulating the flow of sodium carbonate/lime mixtures during the chemical conversion of lithium.
