Knife Gate Valves
 Bi-Directional Knife Gate Valves (KBD)
Product Description
Major Markets: Paper, chemical, power
Design Features: Unique two-stage bi-directional seat
provides dead-tight shutoff in both directions and on deadend
service. Designed for shutoff and isolation services
handling corrosive, abrasive and viscous liquids; abrasive
slurries, pulp stock, and dry materials. Seat design eliminates
pockets that trap process media. Provides maximum flow
capacity. Resilient seats are locked into the valve body and
provide guiding for the gate.

Body Materials: 304, 316 and 317 stainless steel
Valve Style: Bi-directional knife gate, lugged
Actuator Type: Handwheel, chainwheel, bevel gear, cylinder,
electric motor
 Cast Stainless Steel Knife Gate Valves (KGC)
Product Description
Major Markets: Paper, water, wastewater, chemical, power,
steel, mining
Design Features: Cast Stainless Steel Knife Gate Valves are
designed for on-off and isolation services handling corrosive,
abrasive and viscous liquids; abrasive slurries, pulp stock,
and dry materials. The solid cast-bodied full port knife gate
valve features a corrosion-resistant stainless steel body, gate,
stem and packing gland. Improved packing chamber design.
Cast-in guides and jams ensure long-lasting operation.
Resilient seats provide bubble-tight shutoff; metal seats meet
TAPPI Leakage Rate standards. Special v-orifice design available
for throttling applications.
