Hastelloy C-276 Alloy Butterfly Valve

For Extreme Corrosion: Hot Concentrated Nitric & Sulfuric Acids, Wet Chlorine Gas

Key Advantage: Unmatched Metallurgical Defense

When PTFE's temperature or abrasion limits are exceeded, Hastelloy C-276 offers the ultimate defense. This nickel-molybdenum-chromium superalloy provides superior structural integrity and erosion resistance at high temperatures (up to 400°C). It is engineered to withstand the most aggressive media, offering exceptional resistance to pitting, stress-corrosion cracking, and oxidizing atmospheres that would destroy even high-grade stainless steels.

Applicable Media

Concentrated Nitric Acid

Hot Sulfuric Acid

Hydrochloric Acid

Wet Chlorine Gas

Hypochlorite Solutions

Acidic Chloride Solutions

Phosphoric Acid

Formic & Acetic Acids

Case Study: Solving Extreme Corrosion in Nitric Acid Production

"Conventional valves were failing every six months in our 55% nitric acid lines, costing us over \$500,000 annually. JRVAL's Hastelloy valves have eliminated unscheduled downtime and are on track to triple the service life."

PTFE Lined Butterfly Valve

The Go-To Solution for Universal Chemical Service: pH 0-14, Acids, Alkalis, Solvents

Key Advantage: Ultimate Chemical Inertness

PTFE is virtually inert to all chemicals, making it the most versatile and cost-effective solution for a wide range of corrosive media. A thick (3-5mm), isostatically molded PTFE liner completely isolates the valve body from the process fluid, allowing for the use of a robust cast iron or carbon steel body. This provides excellent corrosion protection without the high cost of a full alloy valve, making it ideal for mixed-media systems.

Applicable Media

Mixed Acid Waste

Caustic Soda (NaOH)

Organic Solvents

Pharmaceutical Ingredients

Ultrapure Water

Food & Beverage Products

Chlorinated Water

Aromatic Hydrocarbons

Case Study: Ensuring Purity in a Specialty Chemical Plant

"We handle dozens of different sensitive chemicals. The JRVAL PTFE-lined valves gave us the universal compatibility we needed, preventing cross-contamination and reducing our valve inventory costs by 40%."

FKM (Fluoroelastomer) Seated Valve

The Resilient Choice for High Temperatures, Oils, Fuels, and Moderate Chemicals

Key Advantage: Superior Heat Resistance & Sealing Memory

FKM (e.g., Viton™) excels in applications with high temperatures (up to 180°C) combined with aggressive chemicals, oils, and fuels. Compared to PTFE, FKM offers superior flexibility and "memory," providing a tighter, more forgiving seal in services with pressure fluctuations or light slurries. It bridges the gap between standard elastomers (like EPDM) and high-end solutions, offering an excellent balance of thermal stability and dynamic sealing performance.

Applicable Media

Petroleum Oils & Fuels

Biodiesel & Ethanol

Mineral Acids (Moderate)

Silicone Greases & Oils

Aviation Turbine Fuels

Hot Water & Low-Pressure Steam

Hydraulic Fluids

Animal & Vegetable Oils

Case Study: Eliminating Leaks in a Biofuel Refinery

"EPDM seals were failing in 3 months in our hot methanol lines. JRVAL's custom FKM-seated valves have been running for over 2 years without issue, thanks to their superior material engineering and molding process."
