Meet ASHRAE Standard 102-1989

• Designed with the higher capacity normally required by North American heating systems Valve seat disc, which is made of resilient material (EPDM), ensures tight shut-off 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 Precise and automatic control of room temperature in two pipe systems by modulating the flow of hot water or steam through high-capacity heating units when used with T104 thermostatic actuators Straight body pattern

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.
