Product Overview
The KOZO Hastelloy C276 Floating Ball Valve is intended for highly corrosive chemical and industrial process services where a nickel-molybdenum-chromium alloy is required. The reference product family uses Hastelloy C276 / UNS N10276 pressure-containing components and a compact floating-ball construction for reliable quarter-turn isolation.
Because the ball is free to move slightly downstream under line pressure, sealing load is transferred to the downstream seat. This makes the floating-ball design compact and well suited to small and medium valve sizes.
Why Hastelloy C276?
Hastelloy C276 is a corrosion-resistant nickel alloy widely used in aggressive chemical environments. It is selected for applications involving acids, chlorides and other media that may exceed the corrosion resistance of conventional stainless steels. Final material selection must still consider concentration, nhiệt độ, áp lực , aeration and the complete valve metallurgy.
Key Design Features
- Floating-ball construction: Compact quarter-turn isolation design for small and medium valve sizes.
- Hastelloy C276 body: Reference alloy UNS N10276 for severe corrosive service.
- Flexible seat selection: Seat material is chosen according to process chemistry, pressure and temperature.
- Flanged connection: Reference configuration for integration into industrial piping.
- Automation options: Thủ công, pneumatic or electric actuation can be reviewed according to torque and control requirements.

Material Selection Notes
C276 should not be treated as universally resistant to every fluid. The actual chemical concentration, contaminants, nhiệt độ, pressure and possible galvanic interaction with other materials should be checked before final selection.
Available Configurations
Valve size, pressure class, seat and trim materials, connection style and actuation can be selected to suit the project requirement. For critical service, project-specific inspection, material certification and testing requirements should be stated at the inquiry stage.
How to Specify This Valve
Please provide valve size, pressure class, medium, concentration, design pressure, design temperature, seat material, connection type, actuation method, applicable standards and quantity.
FAQ
What is Hastelloy C276 typically used for?
It is used in many aggressive chemical environments where enhanced resistance to acids, chlorides and localized corrosion is required.
Can the valve be automated?
Đúng. Pneumatic or electric actuation can be considered according to torque, fail-position requirements and plant control philosophy.
Can other pressure classes be supplied?
Đúng, subject to design and project requirements. The DN50 / PN160 configuration is a reference rather than the only available arrangement.
