Resideo T104A1040

High Capacity Thermostatic Radiator Actuator

Achieve accurate and automatic temperature regulation in two-pipe hydronic systems by adjusting the flow of hot water or steam through radiators, convectors, and other high-capacity heating units. The T104A1040 thermostatic actuator is compatible with V110 series valve bodies, providing reliable control for hot water and steam radiators.

Features include:

Conformance to ASHRAE Standard 102-1989 Suitable for controlling hot water or steam-based hydronic heating units Adjustable setpoint dial with guide marks (1-5) and positive shutoff at fully clockwise (0) Incorporates sensor and setpoint dial, with components that can be integral or connected via capillary tubes Resilient EPDM valve seat disc ensures tight shutoff on low-pressure steam or hot water systems Nickel-plated brass valve body with cartridge insert for easy servicing No electrical wiring required for operation All internal parts are replaceable without removing the valve from the system, even under pressure Designed for higher capacity applications typical of North American radiator systems—over twice the flow capacity of most comparable valves

Specifications: Max Temperature (F): 79°F Minimum Temperature (F): 43°F
