Belimo R3015-1P8-P25B2 - 6-way control valve

Belimo R3015-1P8-P25B2

6-way control valve with two sequences for heating and cooling systems. The valve is operated by a rotary actuator through a range of 90°. In the closed position (45°), the integrated pressure relief function compensates for changes in fluid pressure while maintaining separation between the two sequences.
