Severe Service Anti-Cavitation Trim
Engineered for Severe Service – Cavitation-Resistant Trim Solutions
One of the key advantages of Flowserve control valves is the wide selection of severe service trims designed to meet the most demanding plant conditions. In liquid applications with high pressure drops, cavitation can cause serious damage to valve bodies and internals. Flowserve's advanced trim technologies are specifically engineered to eliminate cavitation and ensure long-term performance.
These trims make our valves the ideal choice for critical applications such as:
•Pump Recirculation Systems
•Boiler Feedwater Control
•Condensate and Flashing Services
•Level Control in High-Pressure Vessels
•And many other challenging process environments
For expert guidance on severe service solutions, please contact our sales team.
Flowserve Noise Trim Solutions – Engineered for Quiet, Reliable Operation
In gas and steam services with high-pressure drops, control valves may generate excessive noise that can:
·Exceed occupational health and safety thresholds
·Cause vibration and damage to surrounding equipment
·Disrupt plant operations or nearby environments
To address these challenges, Flowserve offers advanced noise attenuation trims — including MegaStream™, ChannelStream™, and Multi-Z™ — designed to reduce aerodynamic noise through multi-stage pressure reduction and optimized flow path control.
Typical Applications Requiring Noise Trim:
1. Steam Letdown Systems
2. Turbine Bypass and Desuperheater Valves
3. Compressor Anti-Surge and Recycle Valves
4. Natural Gas and Hydrocarbon Vapor Control
5. Boiler Start-Up Valves
Flowserve's noise trim technologies are proven to significantly reduce sound pressure levels while protecting both personnel and plant infrastructure. For guidance on selecting the right trim for your application, contact our technical team.
