 ‘s Slurry Wafer Knife Gate Valve is built with a cast body and features a heavy-duty stainless steel bade. Removable seats on either side of the blade, provide a Bi-directional bubble tight seal, with no metal parts in contact with the slurry.
- 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- When open, the knife-gate is fully withdrawn from the slurry flow.
- No metal parts in contact with the flowing slurry.
- Bubble tight shutoff.
- No clogged bonnet to impede flow.
- External epoxy coated.
- Easily adapted to suit most actuators
- Low maintenance requirements.
All types of actuators can be fitted, electric, gearbox, hydraulic, pneumatic and handwheel.

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.
