SMALL LINEAR THERMOELECTRIC ACTUATORS

Smart-T

PRODUCT DATA

APPLICATION

Smart-T small linear actuators are used in room and zone

applications for time-controlled two-point and pulse-width-

modulated (PWM*) regulation of heating and cooling systems

such as fan coil units, radiators, floor heating systems, chilled

ceilings, and convectors.

 Fit on standard M30 x 1.5 heating/cooling valves,

thermostatic radiator valves, and valve inserts for

manifolds and compact radiators.

 Fit to standard closing dimensions (11.5 mm ± 0.3 mm).

 Special valve adapters on request.

*Recommended controllers: Excel 10 and Excel 12 controllers

(use with other, non-Honeywell controllers may adversely

influence PWM-operation).

FEATURES

 No mounting tools required (easily mounted using

valve adapter)

 Water-protected housing design in all mounting

positions

  Pluggable cable for easy installation and servicing
  Auxiliary switch models for driving pumps or fans
  Normally-open and normally-closed models
  Compact design allows installation in limited space
  Visual indicator showing valve position and type of

action (NO or NC)

  Noiseless operation
  Reliable long-term operation
  Overload protection (4 kV) for 230 V models
