Belimo has added “Control” to the Ball Valve

Belimo has succeeded in solving the problem of the distorted flow characteristic of ordinary Ball Valves. A so-called “ characterizing disc” in the inlet of the characterized Control Valve converts the valve’s characteristic to the equal-percentage kind. The side of the characterizing disc facing the ball is concave and is in contact with the surface of the ball. Thus, the actual flow is regulated by the hole in the ball and by the V-shaped aperture in the characterizing disc.

The Kvs value is reduced and corresponds approximately to that of a Globe Valve of comparable size. In order to avoid having to fit pipe reducers in the majority of cases, each valve size is also available with wide choices of different Kvs values.

Advantages of the Belimo Characterised Control Valve

• Equal-percentage characteristic
• No initial jump in flow on opening
• Excellent stability of control thanks to the characterising disc
• Kvs values similar to those of Globe Valves of comparable size
• Fewer pipe reducers needed
• High rangeability
• High close-off pressure
• Tight-sealing
