designed for abrasive applications
Using materials proven by our extensive experience and installation base in the slurry
transport industry, Weir Minerals has developed the Isogate ® WS series wafer-style valve
to deliver reliability and long term performance.
Its unique design provides ease of maintenance and low overall ownership costs,
delivering outstanding results.
Continuous innovation in material, product design, engineering and manufacturing
ensures that the Isogate
® knife gate valve range remains at the forefront of valve design.
Minerals
The Isogate ® WS series slurry knife gate valve is
specifically designed for a wide range of tough,
abrasive and corrosive applications.
Open Position
Only thick elastomer sleeves
are in contact with slurry. No metal parts contact the fluid. Closed Position
The gate is located in between thick elastomer sleeves, with full tight shut-off.

Maximise safety, reliability and cost efficiencies
with the purpose-built Isogate
® WS series valve
Upper stem cover
Actuation options include: handwheel, bevel gear,
pneumatic, hydraulic, electric (handwheel model shown)
Stainless steel stem Stainless steel
gate guard
Lockout pin
open/close
Single piece
cast body
Load
distribution ring
Stainless steel clevis pin
Packingless top seal assembly including grease channels
Heavy stainless steel gate with tapered tip
Resilient sleeve with reinforcing ring x2 Flush plate
(optional)
Open Bottom
Open bottom allows
for the purging of large
solids, and solids in
higher concentration.
The purging of solids
stops when the gate
is in the full open or
closed position.
Flushing Plate
Flushing plate option
adds flexibilty to the
standard open bottom.
This option also allows
for periodic cleaning of
the lower discharge vent
and can allow flushing
as needed.
Body Options
Design features
• Robust construction ensures long service life
• Two-piece elastomer sleeve design protects flow
areas against corrosion
• Wafer body, narrow pattern minimises
space requirement
• Field replaceable thick elastomer sleeves are easily
replaced without disassembling the valve
• Sleeves incorporate Linatex
® rubber technology,
plus a wide range of elastomer compounds are
also available
• Bi-directional 100% bubble tight shut-off
• Packingless design - no gate or stem packing
• Full port design reduces pressure drop and
turbulence, minimising wear
• Suitable for use in abrasive slurry services with high
percentages of solids
• Open bottom allows for the purging of large solids,
and solids in high concentration
• No seat cavities where solids can collect and cause
gate interference
• Yoke design allows fitting for all designed actuators
• Flush control option allows for periodic cleaning
of the lower discharge vent and allows flushing
as needed

The Isogate ® WS series heavy duty knife
gate valve features an adjustment free
packingless upper seal which eliminates
the need to constantly tighten the packing
to eliminate leakage. The upper seal design
also features a set of lubrication channels
that contain a gate lubricant. A thin layer of
the lubricant is placed on the gate on each
and every cycle. This provides for smoother
gate actuation and increased sleeve life.
Fittings are accessible to recharge upper
seal while in service.
