RF Valves RF-INSAMCOR MH Knife Gate Valves are sealed-design knife gate valves built for demanding slurry, water, and process applications where reliable shutoff and full-bore flow are important.
The MH family features a mechanically retained molded body seal, guided gate travel through the full stroke, and self-cleaning flush-out corners that help reduce buildup in the sealing area.

With an unrestricted flow path and no seat pockets or cavities, these valves are designed to support consistent material movement through the valve body.
Available in Fusion Bonded Epoxy and Soft Rubber Lined configurations, RF-INSAMCOR MH Knife Gate Valves are well suited for industrial and municipal services where abrasion, solids, or challenging operating conditions may be present.
The product family supports multiple actuation options, including manual, pneumatic, electro-mechanical, and hydraulic configurations.
