Fisher™ Cavitrol™ III Trim – Advanced Cavitation Control for Severe Service Valves

Product Overview

The Fisher™ Cavitrol™ III Trim is a high-performance valve trim engineered to tackle the destructive effects of cavitation in severe service applications. Designed for clean liquid services where pressure recovery can lead to cavitation, this trim effectively manages pressure drops up to 207 bar (3000 psi). By incorporating a cage with numerous specially shaped, radially arranged holes, it reduces fluid turbulence and stages the total pressure drop, thereby controlling or eliminating cavitation’s damaging impact. This technology is widely used across power generation, hydrocarbon processing, and other critical industries to extend valve life, reduce maintenance downtime, and enhance process reliability.

Key Features & Benefits

• Superior Cavitation Control: The unique design of the cage holes helps prevent cavitation in properly sized valves, protecting your valve and downstream piping from damage.

• Extended Service Life: Hardened trim materials offer excellent erosion resistance, significantly prolonging the trim’s operational life.

• Easy Maintenance & Inspection: The cage-style trim allows for component disassembly and inspection without removing the valve body from the pipeline, minimizing downtime and maintenance costs.

• Direct Interchangeability: The Cavitrol III single-stage trim is interchangeable with standard trims, allowing for quick retrofitting and upgrades without requiring additional parts.

• Operational Efficiency: The design employs a downward flow configuration and progressively larger flow areas, ensuring that a significant portion of the pressure drop occurs in early stages to help prevent cavitation.

• Proven Reliability: Backed by Fisher’s expertise in severe service solutions, this trim delivers reliable performance in demanding environments like pump recirculation and boiler feedwater systems.

Typical Applications

• Power Industry: Boiler feedwater start-up, condenser recirculation, feed pump minimum flow, and heater drain control.

• Hydrocarbon Processing: Crude unit charge pump recirculation and various refining applications.

• General Industry: Clean liquid applications requiring robust cavitation control.
