NAF Trimball
A control valve for the most difficult applications where high pressure drops are present, causing cavitation, noise and erosion.
- NAF Trimball Z-trim is a name for the ball valves, NAF Duball DL and NAF Trunnball DL, which can be used with a cavitation- and noise reduction trim.
- Z-trim reduces noise and cavitation by taking the pressure drop in several steps. The design allows it to be used with impurities or fibres and have a self-cleaning effect.
- Z-trim also provides a high Cv value and an optimum equal percentage control characteristic.
- DN 50-500, 2″-20″, PN 10-40, ANSI Class 150 & 300
