Belimo R3015-P25-1P8-B2 - 6-way ball valve with control orifice

Belimo R3015-P25-1P8-B2

The 6-way control ball valve with control orifice is used to switch or modulate water flow in heating and cooling elements. It is designed for closed-loop water systems. Two sequences can be operated by one 90° rotary actuator.
