Governing Standards for Slurry - Abrasive Pulp / Mineral Slurry Service
What to Avoid in Slurry - Abrasive Pulp / Mineral Slurry Service
- Ball valves (abrasion in seat area causes rapid failure)
- Globe valves (dead space behind disc traps solids)
- Butterfly valves (disc creates solids buildup upstream)
Service Considerations
- Horizontal installation only - knife gates must not be installed vertically
- Flush connection: injection point upstream of gate for packing flush
- Valve seats and liners should be replaceable in-situ without removing valve from line
- Full-bore bore essential - any port reduction causes velocity increase and accelerated wear
- Settling: never leave slurry valves partially open - always fully open or fully closed
