Cost Effective Knife Gate Valve Solution in USA and Canada

These cost-effective valves typically have sharpened blades to cut through heavy liquids. Knife gate valves are used in wastewater applications where the major issue is corrosion. With the acid-proof stainless steel knife, it requires less maintenance and even replacement. The applications that require completely closed or open position are where knife gate valves should only be used.

The knife gate valves are designed for the on-off services where the valve is completely closed or completely open. These valves are installed in chemical plants, wastewater plants, cement plants, and mining.
