Cement plants demand robust equipment. Learn why heavy-duty cast iron rotary valves are essential for handling abrasive cement clinker and fly ash.

Why Cement Plants Need Heavy Duty Valves

Handling cement, clinker, and fly ash requires rotary valves that can withstand extreme abrasion and high temperatures. Standard valves often fail within months.

Key Features for Cement Industry

  • Abrasion Resistance: Hardened rotor tips and Ni-Hard liners.
  • High Temperature Handling: Bearings isolated from the housing to handle up to 400°C.
  • Robust Drive System: Chain drives or direct drives capable of high torque start-ups.

RALX-HD Series

The RALX-HD (Heavy Duty) series is specifically designed for the cement industry. Constructed from high-grade cast iron with optional tungsten carbide coating, it ensures longevity even in the harshest environments.
