Double Seated High Abrasion Rubber Short Body Slurry Knife Industrial Valve
Pressure rating: PN 1.0 or PN1.6 Mpa
Sleeve material: Natural rubber(Optional)
Temperature range: -30℃～90℃
Max. Temperature: 150℃ For special sleevea
When Full Open
•Knife is positioned above the sleeve
•Sleeves fit tightly to create a pressure pipeline
•No metal parts in contact with flow
•Full bore passageway, good pass through for flow and little pressure drop
•No seat groove for dust collecting
When Full Close
•Knife penetrates the middle of sleeve and shut-off like blind flange and clear out the dust and particle at the same time
•100% bubble-tight seal, zero leakage.
•Double seated design provides bi-directional flow and shut-off.
•Stroke prevent the gate seated at the right positions.
Natural Rubber: superior resistance to tear and abrasion and good resistance to heat build-up
Max. working temperature: 85 ℃
EPDM: Excellent resistance to heat, ozone and sunlight, good flexibility at low temperature, good resistance to alkalis, acids and oxygenated solvents and superior resistance to water and steam.
Max. working temperature: 140 ℃
NBR: Very good at handling petroleum based greases/oils, silicone greases/oils and no oxidizing chemicals. Good resistance to hydrocarbon based fuels.
Max. working temperature: 135 ℃
