Procurement fit

AVK describes the Series 779/91 for general industrial service and suspended solids handling across pulp and paper, power, wastewater treatment, chemical, food and beverage, bulk handling, and mining applications, with a noted operating range up to 120 degrees Celsius and 5 to 10 bar. A separate fixed-liner, duplex-disc model is documented as FM approved for fire-protection service. The procurement record states that the selected valve, materials, configuration, availability, and lead time must be confirmed directly with the manufacturer.

Technical capabilities

The Series 779/91 is a uni-directional wafer-type knife gate valve classified to PN 10 with a cast-iron body, stainless-steel blade, PTFE packing, and EPDM seal. Flange drilling follows EN1092 and the external finish is RAL 3000. Material reference is stainless steel. Documented service temperature is 70 degrees Celsius. The recorded supply length is 000 metres. A second documented variant is described as a fixed-liner, duplex-disc construction with FM approval for fire-protection service, subject to confirmation of pressure rating.

Markets and applications

Documented application sectors for Series 779/91 include pulp and paper, power generation, wastewater treatment, chemical processing, food and beverage production, bulk handling, and mining. The target service is general industrial isolation and the conveyance of suspended solids. A separately documented fixed-liner, duplex-disc model carries FM approval for fire-protection installations. The procurement record indicates that applicability, pressure rating, and thermal limits should be confirmed directly with the manufacturer for each specific project.

Evidence limitations

Detailed dimensional drawings, face-to-face lengths, weight figures, actuator options, and material test certificates for Series 779/91 are not publicly documented. Specific lead times, pricing, and distributor stocking levels are not publicly documented. The full extent of the knife gate valve range beyond Series 779/91 is not publicly documented. The relationship between the 70 degree Celsius service temperature record and the 120 degree Celsius and 5 to 10 bar figure in the procurement note is not publicly reconciled and requires direct manufacturer confirmation.
