Application:

Knife gate valves are suited for several applications e.g. in Mining and Metal Industries, Mineral Processing or Water and Waste Water Treatment. Flowrox can also supply non-standard diameters and special pressures on request. Orbinox and Flowserve are the worlds largest knife gate valve manufacturers, each offering a unique offering of products.

​Features:

  • Integrated load distribution ring; prevents over compression

  • Universal tower design; free interchangeability between actuators

  • One piece body with lockout pins; strong construction without the need for sealing​

  • Full bore

  • Seal tight shut-off

  • Replaceable elastomer ring sleeves

  • ​In the open position only the sleeves are in contact with the medium

Delta's Severe Service Knife Gate Valve is our premier valve. This design didn’t happen overnight though; our team of engineers spent decades improving and perfecting every last detail so that you can be confident it will do what you need it to. The bi-directional zero-leakage design exceeds API, ASME, and MSS specifications all the way up to ASME Class 1500 (3750 psig) – but we’ll go higher if you want us to.

The key differentiation to the Severe Service Knife Gate Valve is the Guided Shear Gate design. Composed of a shearing tip and internal gate guides, this design feature ensures our valve can cut through all media including solids, scale , fiber and paste.. 

SINGLE PIECE VALVE BODY
Unlike the bolted style of the Wey knife gate valve, the Flowrox knife gate valves body is one single piece and takes away the need for sealing between the body halves. The single piece body design does not have an opening or hollow body, so material cannot accumulate in the body cavity.

 

SECONDARY SEAL
The secondary seal is built in the upper part of the body. It provides both wiping and lubricating actions to the gate as it strokes, via contact between the gate surface and the silicone grease in the seal area. Lubrication of the gate allows for easier actuation and movement. There is no need to remove the valve from the line when replacing the secondary seal.

 

RING SLEEVE/SEAT
The ring sleeve offers an integrated load distribution ring that prevents over compression and ensures 100% sealing between the ring sleeve and the valve gate.
