We Are Leading Manufacturer of Pneumatic and Manual Knife Gate Valves in USA and Canada

Valves Only is the leading Knife Gate Valve Manufacturer in the USA and Canada. Knife gate valves are crafted to work in the harsh environment and beneficial for handling slurry, corrosive, viscous and abrasive media. In fully-open position, these valves have minimized pressure drop and relatively low weight.


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.
