Belimo Ball Valves, shut off and Characterised control valves with internal thread fitting for use on warm and cold water systems, bubble-tight shutoff.
The Control Ball Valves guarantee an equal percentage valve characteristic and first-class control characteristics with their unique characterising disc.
The Control Ball Valves from Belimo Automation have set new standards for effective control since their introduction in 1999; tried-and-tested more than 2.5 million times they provide a cost-effective and innovative solution to conventional control valves.
Use the (S2) Actuator with this valve.
