T104 High Capacity Thermostatic Radiator Valve Actuators
Provide precise and automatic control of room temperature in two-
pipe systems by modulating the flow of hot water or steam through
free-standing radiators, convectors and other heating units with
high capacity requirements.
• Continually monitor and adjust room temperature for consistent
comfort and relief from under-heating and overheating.
• Designed with the higher capacity normally required by North
American heating systems.
• Valve seat disc, which is made of resilient material (EPDM), ensures
tight shutoff on steam or hot water systems.
• Nickel-plated bronze casted body with working parts in cartridge
insert for ease of service.
• Controls include sensor, setpoint dial and valve actuator;
components may be integral or connected by capillary tubes.
• Require no electrical connections.
• Meet ASHRAE Standard 102-1989.
• 40 mm collar diameter.
