How to select the best valve for an abrasive slurry application to reduce erosion, cavitation or noise. Commonly used valves such as butterfly, ball and pinch valves wear quickly and are susceptible to cavitation or erosion.

In comparison to traditional ‘line of site’ slurry valves (ball valves, butterfly valves and pinch valves), the SlurryFlo control valve delivers a quantum leap in service life, and reduces the overall cost of ownership for your most demanding applications.

In a diluted froth slurry application, an 8" V-Port Ball Valve required replacement every 4-5 months due to severe erosion. In comparison, SlurryFlo Control Valves provide more than 3 years of continuous service and eliminated damage to downstream piping.

To reduce (or eliminate) the effects of cavitation in slurry, end users can select a SlurryFlo control valve. Our patented trim design centers the high velocity flow and resulting cavitation within the pipe.

Common control valves (such as V-port ball valves) direct high velocity slurry into the valve's body and downstream piping, eroding both. This results in poor system performance, significant maintenance costs, and loss of production.

End users looking to modulate the flow of abrasive slurries must select valves with ‘line-of-sight’ trim geometry, (i.e. butterfly, ball, pinch or knife-gate valves). These designs provide minimal flow re-direction, as they modulate via an increase in the fluid velocity.

SAF engineers recommended replacing the ball valve with a SlurryFlo Control Valve and a downstream RocketPlate to share the required pressure drop and mitigate cavitation. This combination significantly reduced the cavitation and vibration.

Explore case studies from customers who have increased their application's performance by replacing traditional slurry control valves such as v-ball, butterfly or pinch valves with custom engineered SlurryFlo control valves.

Our small diameter control valves incorporate a unique wear technology to provide long-lasting erosive flow control. In place of hard coated metal parts, the gate and seat plate are made entirely of sintered tungsten carbide.

The following summary describes the fundamental differences between a SlurryFlo linear control valve with Sintered Tungsten Carbide trim, and common slurry control valves with Ceramic trim (such as a V-port ball valves, plug valves or butterfly valves).
