RF Valves RF-INSAMCOR PB Ported Blade Knife Gate Valve

RF Valves RF-INSAMCOR PB Ported Blade Knife Gate Valves are sealed-design knife gate valves built for challenging wet or dry service where reliable isolation and solids-handling performance are required.

The PB design uses a ported blade that remains in contact with replaceable elastomer sleeves on both sides, supporting bi-directional flow and shutoff. Its pass-through design with standard catch chamber helps reduce areas where unwanted solids can collect and interfere with full gate closure.
