High Performance Butterfly Valve – McCannalok Series, Metal Seated, Double Offset Design

The McCannalok High Performance Butterfly Valve is engineered for high-pressure, high-cycle, and critical shut-off applications across diverse industries. This valve features a double-offset disc geometry, which reduces seat wear and improves service life. It ensures zero-leakage, bi-directional sealing and is suitable for both throttling and on/off control.

Constructed with robust materials and available in both metal and soft seat configurations, the McCannalok valve is ideal for steam, chemical, hydrocarbon, and power generation systems. Its precision-engineered seat and stem design enable reliable, repeatable performance even under thermal cycling and vibration.

This valve is certified for fire-safe operation and is compatible with manual, pneumatic, electric, or hydraulic actuation systems, offering flexibility for various process requirements.
