Delta Knife Gate Valves -Severe Service

​Delta Industrial™ knife gate valves have been the market leader in shear gates for many years.


Unlike many other high-pressure and heavy-duty knife gate valves, Delta Industrial™ valves provide bi-directional zero-leakage isolation and offer long-term performance with exceptional isolation results, protecting your people, plant and environment from process fluids.

Delta Industrial™ valves are designed specifically to handle heavy-duty, abrasive and high-temperature slurry applications with an innovative design, industry-leading performance, customizable features and absolute dependability.

They are made from a wide range of materials to help eliminate any corrosion or erosion, while their closed-body design with top transverse seal eliminates leakage to the environment during operation. They also contain a hardened, beveled edge gate design which allows the knife gate to crush, cut and expel solids that may be in the fluid stream.



Compared to other types of knife gate valves, our Delta Industrial™ valves offer the following benefits:

  • Bi-directional, zero-leakage shut-off

  • Packingless design. Transverse seal, no gate or stem packing

  • Enclosed body prevents leakage to the environment

  • Seal retained out of the flow stream and flush with the bottom port

  • Full port flow reduces pressure drop and turbulence, thus minimizing wear

  • Fully guided, beveled-edge machined gate shears through obstructions in flowing media

  • No seat cavities where solids can collect and cause gate interference

  • Will operate under vacuum conditions

  • Yoke design allows fitting for various designed actuators

  • Available with optional coatings, wear rings and overlays for tough slurry duties
