Features & Benefits
Thick Bonded Rubber Liner
3 to 6 mm thick rubber liner is chemically bonded to the body, providing a protective barrier against abrasive slurry and corrosive chemicals.
Abrasion-Resistant Disc Coating
SS316 disc with electroless nickel plating, chrome plating, or polyurethane coating resists erosion from high-velocity slurry particles.
Replaceable Liner
Rubber liner can be replaced in-line without removing the valve, reducing long-term maintenance cost.
Gear Operator Standard
Gear operator is standard for all sizes in abrasive service, providing controlled open/close speed and preventing the rapid disc movement that causes liner damage in lever-operated valves.
Wide Chemical Compatibility
EPDM, NBR, Viton, and Hypalon liner options cover a broad range of chemical services.
Bi-Directional Flow
Symmetrical disc and liner design allows installation in either flow direction, simplifying piping design.
