Clarkson KGF High Pressure Slurry Knife Gate Valve

High pressure slurry design with elastomer sleeves providing proven performance up to 300 psi.

The Clarkson KGF and KGF-HP slurry knife gate valves provide proven slurry valve technology in higher pressures

Key Features

High pressure designs for the most challenging applications:
KGF: 20 bar (300 psi) CWP optional gate provides 31 bar (450 psi) CWP
KGF-HP: class 300 (51 bar [740 psi] CWP)
100% isolation bubble-tight shut-off results in absolute zero downstream leakage.
Double-seated design provides bi-directional flow and shutoff.
Field replaceable elastomer sleeves.
Dynamic, self-adjusting secondary seal.
Unobstructed flow helps eliminate turbulence and minimizes pressure drop across valve.
No seat cavity where solids can collect and prevent full gate closure.
No metal parts in contact with the flowing slurry.
No gate or stem packing is required, eliminating packing leakage and maintenance.
Adaptable frame (yoke) design, featuring a top-removal stem nut, can be field modified to an air cylinder or bevel gear in the field.
