Knife gate valves

Knife gate valves are linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. They are one of the most common valves used.

Knife gate valves are advantageous in applications involving slurries, as their “gates” can cut right through the slurry. They are also used in applications that involve viscous liquids such as heavy oils, light grease, varnish, molasses, honey, cream and other non-flammable viscous liquids.  The knife gate valves are available in large sizes to better handle thick flow.

However, knife gate valves do have low-pressure limitations, and are not optimal in applications that require cleanliness or sanitary conditions. They are excellent for use anywhere a shutoff valve is needed.

When needed, the knife gate valves can also be used where throttling capabilities are desired, although this is not generally recommend.
