Advances in control valve trim manufacturing are set to alleviate cavitation issues that are costing process and industrial plants thousands of pounds’ maintenance, repair and operational (MRO) spend.

Linear trim means that the valve flow rate is directly proportional to the valve position. For example, if the valve is 50% open, the flow rate is 50% of the maximum.

Emerson announced its Fisher Whisper Trim Technology for use in both rotary and globe valves that addresses noise issues. Control valve noise is created by high pressure drops across a valve, which ...

In addition to the expanded line-up of Fisher dirty service control valves, the Fisher Cavitrol™ III Trim with improved sealing technologies is available. It is a multi-stage (2 or 3 stage) trim ...

The engineers solved the problem using a new Retrofit3D DRAG trim to reduce the velocity of fluids exiting the valve. The disk stack that was used was manufactured using IMI Critical’s Retrofit3D ...

1", 1-1/2" & 4" Fisher NotchFlo™ DST control valve trim are added to Emerson’s cavitation package MARSHALLTOWN, IOWA (April 17, 2003)--Emerson Process Management today introduced the 1", 1-1/2" & 4" ...

The RTK REflex QC control valve with balanced trim compensates for high differential pressures within the trim. Circor, has released its RTK REflex QC control valve with balanced trim which ...

A severe-service control valve, the Multi-Z, is designed specifically to handle high-pressure drop applications in which entrained solids are a problem. The Multi-Z is well-suited for system start-up ...

Most process control valves for flow, pressure, and level control are specified with equal percentage trim. The recommended procedure for specifying control valves involves first understanding the ...

To mitigate cavitation related downtime, IMI Critical Engineering has developed the 840-3D (globe) and 860-3D (angle) control valves. Featuring a customisable 3D-printed trim that uses IMI’s patented ...
