ORBINOX HG Slurry Knife Gate Valves Perfect Choice for Filter Presses

Before ORBINOX HG valves were installed in, this mining company was facing some issues with its former valve supplier. Former valves couldn’t last for more than 6 months. They asked ORBINOX for a solution that could work for at least 8 months and for more than 12.000 cycles.

Valves should work under the following process conditions:

• High filter capacity
• Pressure: 21 bar
• Temperature: ambient
• Solid %: 52-57
• Solid size: fines
• Cycles: 50 times/day

ORBINOX Brazil subsidiary together with the Mining Segment Manager studied the case and came up with the following solution:

• HG slurry high pressure knife gate valve
• Size: DN 200/8”
• PN25 rating
• Body: Ductile Iron
• Gate: 316SS
• Sleeves: NR
• Actuator: Pneumatic

HG slurry high pressure knife gate valves are still performing well after 7 months. For this reason, the mining company has decided to replace all the existing valves from previous suppliers and install ORBINOX HG knife gate valves in all of the Filter Presses.
