3-Way Switching and Design

The 40 series valves provide versatile flow control options. A key design advantage is the ease of packing adjustment, which can be performed while the valve remains inline, reducing downtime during maintenance. This specific model is configured for switching service, allowing for efficient flow redirection between three ports.

Inline Maintenance

The one-piece design is engineered for straightforward packing adjustment without removing the valve from the system piping.
