UNI - MOD X is an electric actuator designed for operating 2,3 and 4-way valves. Actuators are controlled by modulating signal 0-10V. Actuators have output signal. FIRŠT UNI-MOD X actuators allow high regulating accuracy and easy installation with different mounting systems.

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

Actuators UNI- MOD X are recommended for mixing or diverting applications with FMV 130 / 130C, FMV 140 / 140C, FMV H-151 / H-151C valves and FMV G-130 / G-140 valves. Actuators can also be used with 2-way FBV 600, FBV 200C, FBV 200C-M and 3-way FBV 230C valves. It also can be assembled on 2-way and 3-way ISO 5211valves.

It is also equipped with mounting kits for assembling on mixing valves of other manufacturers: ESBE, LK, BARBERI, FEROTHERM, PAW, DANFOSS, BESSER, SELTRON, LOVATO, TUXHORN, STRAWA, IVAR, HONEYWELL.
