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
Cast iron FBE coated body with replaceable sleeves and gate
Optional actuation: hand wheel, manual gearbox, pneumatic, hydraulic and electric
Optional accessories: proximity switches, solenoid valve, junction box
Pressure Rating – Optional gate materials can be used to increase the pressure rating of
the Insamcor SKG F and SKG W to 200 psi (14 bar) depending on the
valve size and application
Sleeves – EPDM, FKM/FPM or NBR
Gate – Different gate materials available on request.
Actuators – Manual bevel gear, pneumatic, electro-mechanical and hydraulic
Retainer flanges – Standard on the SKG F for 10” (DN250) and larger sizes
Purge Ports – Removable bottom cover with flush-out connections
