ZFI series valves are uni-directional, full lug design and manufactured as per MSS SP-81
standard and TAPPI TIS 405-8 standard for Industrial service applications. The ZFI series design
assures non-clogging shut-off of suspended solids.
The ZFI series Knife Gate Valve can be used for liquid, solid-liquid mixes / slurries, dry bulk solid
applications. These valves are provided with full bore (100%) opening which does not restrict the
flow of the media in pipeline.
Resilient seated valves offer a leak tight shutoff. Metal seated valves offer leakage within
permissible limits as per MSS SP-81 standard.
ZFI Series Knife Gate Valve Features:• A full lug type design available in ANSI B16.5 (class 150) / DIN PN 10 / PN 16 flange drilling and
other standards available.
• Investment cast up to 16” diameter.
• Sealing configurations: integral metal seat / resilient seat locked in place by a stainless steel
retainer ring.
• Sealing achieved by means of welded jams pushing the gate on to the seat for full face contact
between gate and seat.
• Gate having beveled knife-edge to cut through solid particles settled at bottom of body and
achieve full closure.
• Self lubricated packing gland.
• Packing: PTFE Impregnated Synthetic Fibre with EPDM O-ring.
• Rising stem as standard / Non rising stem is available on request.
• Operating options: Hand wheel / Hand Lever / Bevel Gear / Pneumatic Cylinder / Electric
Actuator & Hydraulic Cylinder.
The ZFI Series Valves are available in the following Sealing Configurations:• ZFI-M: Integral metal seat.
• ZFI-S: Resilient seat retained by stainless steel ring.
