Cast Iron Lugged Knife Gate Valve PN16 Unidirectional

The Cast Iron Lugged Knife Gate Valve PN16 Unidirectional gives you reliable isolation in demanding industrial pipework. The lugged and tapped body suits PN10/16 flanges. Furthermore, the unidirectional gate cuts cleanly through slurries, solids, and wastewater. The lugged pattern also lets you remove downstream piping without disturbing the valve body. For the full range, see our Knife Gate Valves collection.

Eight size variants are available from 2" to 8". The 8" size comes in both PN10 and PN16 rated versions. Consequently, you can match the valve to your specific system pressure class.

Key Features of This Cast Iron Lugged Knife Gate Valve Unidirectional

Applications for a Cast Iron Lugged Knife Gate Valve PN16 Unidirectional

This unidirectional PN16 cast iron knife gate valve suits municipal wastewater systems, industrial effluent lines, and slurry pipework. In addition, the knife gate action handles thick or solid-laden media where a standard gate valve would struggle. Moreover, the lugged body gives a stable mount between flanges. It therefore suits high-stress pipeline systems where secure isolation is critical.

Pressure and Temperature Ratings

This cast iron lugged knife gate valve carries a PN10 or PN16 pressure rating depending on the size selected. The temperature range is -20°C to +110°C. However, always confirm both the pressure class and temperature of your system before specifying. The 8" size is the only variant available in both PN10 and PN16 options.

Selection Advice

Match the valve size and pressure class to your flange standard and system requirements. As a result, you get a secure, stable fit without adaptors. If you need a bidirectional knife gate or a different body material, see the full Knife Gate Valves range for alternatives.
