Ball segment valves

Ball segment valves – high capacity and linear control characteristics in control applications

High capacity, excellent tightness and free flow. These words aptly describe some of the superior properties of the ball segment valve. Somas ball segment valves have been designed to fulfill the strictest requirements of the process industry. Due to its free flow and choice of different materials for its housing and seat, the ball segment valve is usually the best choice for the industry.
