Double Flange Mining Knife Gate Valve Bi - Directional Seal Full Port Air Operated

Double Flange Mining Application Bi-Directional Seal Full Port Air Operated Knife Gate Valve

TEKO Slurry Knife Gate Valve is built with fabricated body and features a heavy-duty of stainless steel blade. Removable seats on either side of the blade provide a bi-directional bubble tight seal with no metal parts in contact with the slurry.

Features

• 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• When open, the knife-gate is fully withdrawn from the slurry flow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
• Bi-directional flow
• Suitable for wet or dry service
• No Gland to maintain.
• Wide range of elastomers available
• No seat cavity where solids can collect and prevent full gate closure

Specifications

How the slurry knife valve works

Gate positioned above seals

Tight fit between sleeves and the internal sleeve profile contain the line pressure

Metal parts not in contact with slurry

Unobstructed port area eliminates turbulence, minimizes pressure drop across valve

No seal cavity where solids can collect and prevent full gate closure

Closed Position

Gate travels through sleeves to provide blind flange shut off and expel solids, allowing complete closure

100% isolation-bubble tight shut-off results in absolutely zero downstream leakage

Double-seated design provides bi-directional flow and shut-off

Sleeve profile and tight fit between sleeves and gate contains internal pressure

Controlled stroke prevents gate from penetrating too far, minimising stress on sleeve
