Resideo V110E1012 Thermostatic Radiator Valve Body 3/4

The Resideo V110E1012 is a 3/4" NPT angle-pattern thermostatic radiator valve body designed for two-pipe hydronic and steam heating systems. Constructed of nickel-plated bronze with 3/4" NPT inlet and outlet connections, it delivers a 162,000 BTU/hr capacity and operates across a 32°F to 248°F temperature range. It is rated for 150 psi hot water service and 15 psi steam service, making it suitable for residential and commercial boiler-fed radiators, convectors, and heating units. Dimensions are 1 1/8" x 2 5/8". This valve body requires a T104 thermostatic actuator to function and serves as an OEM replacement for existing angle-pattern radiator valves. Installation is rated professional-required; use PTFE thread seal tape and a pipe wrench during installation, and the MT110C1011 service tool is recommended for servicing. Typical failure symptoms addressed by replacement include rooms not regulating temperature, radiators running too hot or cold, a valve stuck open or closed, or water leaking from the valve body.
