Overview

High Capacity Thermostatic Radiator Valves with T104 Actuators provide control of temperature by modulating the flow of hot water or steam through free-standing radiators, convectors and other heating units with high capacity requirements.

Features

  • 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.
  • All working parts are replaceable using service tool (MT110C1011) while valve remains in service, in-line, under pressure.
  • Valves normally open without control mounted.
  • Valves may be used with T104 Thermostatic Actuators.
  • Meet ASHRAE Standard 102-1989.
