COMP-MOD is an electric actuator designed for operating 3-way and 4-way rotary mixing valves. Actuators are controlled by a modulating signal. FIRŠT COMP-MOD actuators allow high regulating accuracy and easy installation with quick fit system.

Actuators are available in 24 V AC 50 Hz and are supplied with a 1m attached connection cable. Actuator can be manually operated with button on the cover. Actuator can be optionally fixed to the valve with additional screw. 

COMP-MOD actuators are recommended for mixing applications with FMV 130 valves, FMV 140 valves from DN 15 to DN 32 and FMV H-151 valves.
