Critical Service / Abrasive & Slurry
Abrasive and Slurry Valves Designed Around Solids, Velocity and Wear
Hard-faced seats and wear-resistant designs for ash handling, mining and solid-particle flow.
Selection basisSolids + size + hardness
Design routeProtected trim + clear flow path
Typical solutionMetal-seated ball / hard-faced gate
Engineering focus
Design out the dominant failure risks
Define solids, particle size and hardness, density, velocity, settling and cycles, then protect the flow path and sealing surfaces.
Cavity buildup
Solids can increase torque and block movement.
Seat damage
Trapped particles can score seats and prevent shut-off.
Valve selection
Match the architecture to the duty
Starting points for engineering review. Final selection depends on the completed process data and project specification.
Metal-Seated Ball Valve
Best fit: Fast abrasive-fluid isolation.
Engineering focus: Hard coating, seat scraping and torque margin.
Hard-Faced Gate Valve
Best fit: On/off slurry duty with direct flow.
Engineering focus: Gate edge, guides and replaceable wear parts.
Knife Gate Valve
Best fit: Lower-pressure slurry and solids handling.
Engineering focus: Seat type, packing and containment.

Buyer FAQ
What particle data matters?
Concentration, size distribution, hardness and shape.
Why can actuator torque rise?
Packing friction, buildup, scraping and Δp add load.
Should wear parts be replaceable?
Replaceable trim can reduce lifecycle cost and downtime.
