SKG Wafer

A low maintenance product with field replaceable heavy-duty sleeves and gate

OVERVIEW

SKG’s purpose is to solve typical and perennial valve problems. We achieve this by providing quality valves that provide the lowest cost of ownership and operation, highest reliability and minimum lifetime maintenance.

SKG range of wafer and flanged knife gate valves features a packingless design, replaceable elastomer sleeves and a fully enclosed yoke for severe slurry applications.

150 psi CWP (10 bar) pressure rating for all sizes

Bi-directional flow and shut-off resulting in zero downstream leakage

No metal parts in contact with the flowing media when the valve is in the fully open position

No seat cavity or unwanted solids to build-up and prevent full gate closure

Field replaceable heavy duty elastomer sleeves

Suitable for wet or dry service

A yoke design which consists of two yoke plates that fully encloses the gate, spindle and clevis.

Standard bellows provide additional protection for the spindle against scoring from abrasive particles

Standard open and closed indicators

Standard provision for lockouts in the open and closed position

The top bracket is designed to accept manual, pneumatic or electric actuation for easy conversion in the field
