3-way diverting/changeover unit with Clip system

The S9000-DIV is an electric motor actuator designed for operating rotary diverting valves (FDV 231C, FDV 232C, FDV 233C). Actuators are controlled by 2-point signal (SPST) with built-in relay module. Unit can be manually operated.

Valves are available in DN 15 – DN 25, with internal or external thread or compression fittings and are rated PN10.

FIRŠT S9000-DIV actuators with FDV 231C,232C and 233C valves are designed for use in radiator, floor or remote heating systems and other small and medium sized heating or cooling systems.

Three types of connections are available: internal thread (FDV 231C), external thread (FDV232C) and compression fittings (FDV 233C).
