The Belimo R3015-1-1-B2 regulating ball valve is a 6-way valve with an internal thread, designed for closed water systems. It allows two sequences (typically cooling and heating) to be operated by a single rotary actuator within a 90° range. The valve supports both switching and continuous regulation on the water side in heating/cooling elements. In the closed position, it has an integrated pressure relief function to compensate for changes in liquid pressure due to temperature.
