Characterised 20mm 2 Port Valve Kvs 6.3 – Suitable Actuators LR../LRF..




Belimo Ball Valves, shut off and Characterised control valves with internal thread fitting for use on warm and cold water systems, bubble tight shut off.

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 the Valve.
