Slurry Valve FAQ Section
Q: What makes your slurry valves suitable for abrasive applications?
A: Our slurry valves feature specially hardened materials in all wetted components, including chrome-plated discs and reinforced elastomer seats. The unique geometry of the flow path minimizes turbulence that accelerates wear, while the double-seat design provides secondary protection against leakage even under extreme abrasive conditions.
Q: How often should slurry valves be maintained?
A: Maintenance intervals depend on operating conditions, but we recommend quarterly inspections for valves handling highly abrasive media. Our design allows for easy replacement of wear components without removing the entire valve from the pipeline. Critical components like seals and seats typically last 12-18 months in continuous service with abrasive slurries.

Slurry Valve Applications
| Industry | Typical Service |
|---|---|
| Mining | Ore slurries, tailings, processing chemicals |
| Power Generation | Flue gas desulfurization, ash handling |
| Chemical Processing | Catalyst slurries, abrasive chemical mixtures |
| Wastewater Treatment | Sludge control, grit removal systems |
Slurry Valve FAQ Section
Q: Can your slurry valves handle both acidic and alkaline slurries?
A: Yes, we offer multiple material options to suit various pH conditions. Standard configurations use high-grade stainless steel for neutral to mildly corrosive applications. For highly acidic or alkaline slurries, we recommend our super-duplex stainless steel or specially lined versions with PTFE or other chemical-resistant linings. Our engineering team can help select the optimal material combination based on your specific process chemistry.
Installation Guidelines
- Install valves with adequate clearance for actuator operation
