High Performance Slurry Knife Gate Valve is
built with a fabricated steel body and features a
heavy-duty stainless steel bade. Removable seats on
either side of the blade, provide a Bi-directional
seal and deflection cones are available in a wide
range of polymers and hard FACW materials, ceramic
coating is optional. A port at the base and tower
section of the valve body allows for flushing.
- Double Seat design for heavy
duty slurry service.
- Ease of replacement of seat
liners.
- When open, the knife-gate is
fully withdrawn from
the slurry flow
- Face-to-face can be altered to accommodate
different lengths of other valves. Pinch, KGV, Ball,
Diaphragm, plug or Gate valves.
- No clogged bonnet to impede
flow.
- Low maintenance requirements.
- Suitable for wet or dry service.
- Bi-directional flow.
- No gland to maintain.
- No internal gate guides.
- Light weight for easier handling.
- Indicator to show open or closed
position, or for
limit switches

Matching rubber inserts are placed in the valve
housing to seal against the gate when the valve is
closed and seal against each other when the valve
is open. This tight seal contains the high internal
line pressure, precluding direct pressure against
the secondary seal.
Double seated design provides bi-directional flow
and shut off.

- Mining and mineral processing
- Power generation
- Sand and gravel
- Chemical and soda ash
- Pulp and paper
- Environmental and Effluent
All types of actuators can be fitted,
electric, gearbox,
