Giacomini's thermo-electric actuator is designed to ensure optimal room temperature control on thermostatic valves, manifolds and zone valves. With limit microswitch, this version is normally closed (N.C.) and powered at 230V, combining energy efficiency, quiet operation and long life due to the absence of mechanical parts subject to wear:

  • Power supply: 230V, frequency 50 Hz, 4-core cable with limit switch, length 1 metre

  • Voltage-free status: Normally closed (N.C.)

  • Microswitch: Normally open with valve closed, for versions with limit switches

  • Connection: Quick-connect system for standard Giacomini valves and manifolds

  • Mechanical indicator: Actuator position display

  • Linear motion: Slow closing to eliminate water hammering

  • Power consumption: Low power consumption with maximum power 2.5W

Todo correcto A muy buen precio la verdad muy bien

Ottimo prodotto, come da descrizione di qualità .

Todo perfecto. Llego a España en apenas unos días.

Valvole un tantino problematiche.... a volte rimangono bloccate dopo lo spegnimento estivo dell'impianto.

Ricevuto l'articolo qualità prezzo direi ottimo
