NAF Trimball
The NAF Trimball represents a new approach to addressing cavitation, erosion, and high noise levels in control valves. The patented design, based on the well-established NAF-Duball ball valve, combines the benefits of an advanced control valve with the simplicity of a ball valve.
It features a ball with zigzag channels offering major control benefits, and a floating ball design that prevents vibrations from being transmitted to the stem and actuator, even at high differential pressures. The NAF Trimball is CE-marked according to Pressure Equipment Directive (PED 97/23/EG) module H, category III.

Technical Data
- Size Range: DN 50-450 (2″)
- Pressure Rating: PN 10-40 (ANSI Class 150, 300)
Advantages
- Z-trim reduces noise and cavitation by taking the pressure drop in several steps.
- Easy-to-service arrangement allows for quick replacement of the ball and seals without removing the stem and actuator.
- The floating ball design prevents vibration transmission to the stem and actuator.
- A-trim offers the highest noise reduction for clean media, with a design that opens channels gradually to manage flow.
Industries
- Bleach Chemicals
- Digester
Applications
The NAF Trimball is a control valve specifically designed for challenging operating conditions where cavitation, noise, and erosion are concerns. It is suitable for a wide variety of applications that involve demanding media and difficult pressure conditions.
