Trimball Control Ball Valve

Brand: Flowserve NAF AB

The NAF-Trimball represents an entirely new approach for addressing the problem of cavitation, erosion and high noise level in control valves. 

The patented designs, which is based on our well-established NAF-Duball ball valve, combines the benefits of an advanced control valve with the simplicity of a ball valve.
Features
  • A ball with many zigzag channels which offers major control benefits
  • Z-trim makes pressure drops in 5 steps
  • An easy-to-service arrangement, due to the off-center joint face of the body, which allows for easy replacement of the ball and seals, without the need for removing the stem and actuator
  • A floating ball, which means that no vibrations are transmitted to the stem and actuator, even at high differential pressures
