HC276 National Standard Flange Ball Valve

Description

The HC276 National Standard Flange Ball Valve is a premier fluid control solution engineered for environments where standard stainless steels and even duplex alloys fail. Constructed from Hastelloy C276 (UNS N10276)—a nickel-molybdenum-chromium superalloy—this valve is virtually immune to a wide range of corrosive agents, including wet chlorine, hypochlorite, and strong oxidizing acids. Its ball-and-seat design allows for a quick 90-degree shut-off, and the National Standard (GB) flange ensures seamless integration into domestic and international piping systems requiring high-integrity flanged connections.

Features

• Universal Corrosion Resistance: Exceptional performance in both oxidizing and reducing atmospheres, with specific resistance to pitting and stress corrosion cracking.
• Full Port Design: Provides maximum flow capacity and minimal pressure drop, ideal for high-viscosity or slurry-laden media.
• Blow-out Proof Stem: Internal entry stem design ensures the stem cannot be ejected under high pressure, enhancing operator safety.
• Fire-Safe & Anti-Static: Equipped with specialized sealing and grounding features to prevent hazardous discharge in volatile environments.
• Low Operating Torque: Precision-ground ball and high-quality PTFE or PEEK seats ensure smooth actuation even after long periods of inactivity.

Specifications

Applications

• Chemical & Petrochemical: Handling concentrated sulfuric, hydrochloric, and phosphoric acids.
• Pulp & Paper: Bleaching systems using chlorine dioxide and hypochlorite solutions.
• Waste Treatment: Processing aggressive industrial effluents and hazardous chemical waste.
• Flue Gas Desulfurization (FGD): Resisting scrubbers and heat exchangers in power plant emissions control.
• Pharmaceuticals: High-purity chemical synthesis where alloy integrity is critical to prevent batch contamination.
