Carbon Steel Triple Offset Butterfly Valve with Gearbox

This valve delivers tight shut-off in demanding pressure and temperature applications. The triple offset design positions the disc and seat so that closing the valve creates a bubble-tight seal without friction between the components, extending seat life and reducing wear compared with standard butterfly valve designs.

Flanges on both ends allow direct bolting into pipework, providing a secure connection for isolation duties across steam, high-pressure water, hot oil, compressed air and gas distribution systems. The metal-seated construction withstands higher temperatures and more demanding conditions than resilient-seated alternatives, making it suited to processes where reliable isolation is critical.

The worm-gear operator gives smooth, controlled operation, allowing the valve to open and close with reduced effort even in larger sizes. This manual gearbox arrangement suits installations where space or access limits the use of actuated alternatives, while still delivering precise control over flow.

Applications:

• Steam systems
• High pressure water systems
• Hot oil systems
• Compressed air systems
• Gas distribution
• Process fluid isolation
• Tank farms
• Utility services

Summary:

• Triple offset disc and seat geometry for bubble-tight sealing and long seat life
• Metal-seated construction suited to high temperature and high pressure duties
• Double flanged connection for direct installation into pipework
• Manual worm-gear operator for smooth, controlled operation
• Suitable for isolation and shut-off across a wide range of industrial processes
