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 ...

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 ...

For the Rotary/¼-Turn Control Valve types, there are not many trim style choices of note to discuss that influence initial valve selection. However, for the Globe Style Control Valve, there are a few ...

This accuracy is achieved by testing, modification and retesting of the control valve trim. Stephen Freitas [email protected] A: Flowserve have had such a device for a decade; the current StarPac 3 ...

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 ...

Emerson’s New Valve Trim Technology Improves Noise Reduction and Flow Efficiency Nov. 1, 2023 - Emerson has announced its innovative new Fisher Whisper Trim Technology for use in both rotary and globe ...

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 ...
