COMPACT is an electric actuator designed for operating 2-way and 3-way valves. Actuators are controlled by 2-point SPST signal built-in relay module. FIRŠT COMPACT actuators allow high regulating accuracy and easy installation with one-click CLIP system or flexible holder system.
Actuators are available in 230V AC 50 Hz / 24V AC 50 Hz and are supplied with a 1,5m attached connection cable. Actuator can be manually operated (4230). COMPACT actuators are recommended for on/off applications.
Actuators 4230 with FBV 200C (DN15 - DN32), and actuators 4930 with FBV 600 valves (DN 15- DN 32). Compact actuators can also be used for diverting applications. Actuators 4950 with FBV 230C-L valves. Anti blocking function provides that in case of blockade the motor changes its direction. Because of that feature, the motor is able to save itself from stopping.
