3PC Ball Valve HC276 (Hastelloy)

Description

Hastelloy C276 (UNS N10276) is a nickel-based “super-alloy” designed for maximum reliability in severe service:

• Stability in Harsh Acids: Proven durability in strong solutions of oxidizing salts, such as ferric and cupric chlorides, as well as hot contaminated mineral acids.
• Elite Resistance to Oxidizing & Reducing Media: Exceptional performance in a vast range of chemical environments, including wet chlorine gas, hypochlorite, and chlorine dioxide.
• Superior Pitting & SCC Defense: The high molybdenum and chromium content provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in high-chloride conditions.

Features

• Modular 3-Piece Design: The central body section can be “swung out” by removing a few bolts, allowing for internal cleaning, seat replacement, and maintenance without fully disconnecting the end caps from the pipeline. This significantly reduces downtime.
• In-Line Serviceability: Because the pipe connectors (end caps) remain attached to the line, the 3PC design is the preferred choice for welded systems where valve removal is difficult.
• Full Bore Flow: Provides an unobstructed flow path that matches the pipe’s inner diameter, ensuring zero flow restriction and minimal pressure drop.
• Precision-Engineered Sealing: High-integrity PTFE or RPTFE seats combined with a mirror-polished HC276 ball ensure a bubble-tight shut-off even after thousands of cycles in aggressive media.
• High-Pressure Capability: The 3-piece bolted construction offers superior structural rigidity, making it suitable for high-pressure industrial applications.

Specifications

Applications

• Chemical & Petrochemical: Handling strong oxidizers, organic chlorides, and acetic acid.
• Pulp & Paper: Bleaching sections using chlorine dioxide or hypochlorite.
• Waste Treatment: Processing of highly toxic and corrosive industrial effluents.
• Pharmaceutical: Clean-service applications where material inertness is vital for batch purity.
