Total Flow Control Solutions

Features

Meets a wide range of abrasion,

corrosion, temperature, and pressure

requirements.

May be used in wet or dry services

easily dealing with large, heavy

particles and tramp material.

Heavy-duty, field replaceable

elastomer sleeves.

No metal parts in contact with the

flowing slurry. Unobstructed flow eliminates

turbulence, minimizes pressure drop

across valve.

100% Isolation; bubble-tight shut-off

results in absolutely zero downstream

leakage.

Double-seated design provides

bi-directional flow and shut-off.

No seat cavity where solids can

collect and prevent full gate closure.

No gate or stem packing is required,

eliminating packing leakage and

maintenance.

Adaptable frame (yoke) design

featuring a top-removal stem nut.

General applications

Features

How the KGA sleeves work: Matching sleeves are placed in the KGA valve housing to sealagainst the gate when the valve is closed and seal against each other when the valve isopen. As the gate moves from open to closed position, it separates the facing sleeves. Astiffener ring molded into the elastomer retains the roundness of the sleeves during openingand closing cycles. The unique KGA sleeve assembly provides positive sealing action whenthe valve gate is closed. When the gate is open, the sleeves provide an unobstructed portand protect metal parts from the flowing slurry.

Open position:

Gate positioned above seals

Metal parts not in contact with slurry

Unobstructed port area eliminatesturbulence, minimizes pressure dropacross valve

No seat cavity where solids can collectand prevent full gate closure

Closed position:

Gate travels completely through sleevesto provide blind flange shut off and expelsolids.
