## Long description

Thermostatic Radiator Valve Sourcing V81112Q 1/2" x 3/4" 40 mm is a thermostatic control valve for use on radiators and convectors in hydronic heating systems. The valve is designed to regulate flow to maintain a set room temperature and to allow isolation of the radiator for servicing. It fits standard valve bodies and is intended for installation where a compact 40 mm valve body is required.
Advantages
The valve provides thermostatic control that automatically adjusts flow according to the set temperature, reducing manual intervention. Its compact 40 mm valve body supports installation in tight spaces while maintaining reliable sealing and flow regulation. Compatibility with common radiator and convector connections simplifies replacement and system upgrades.
Suitable for
Hydronic central heating radiators
Fan convectors in residential and light-commercial buildings
Replacement of existing thermostatic radiator valves with 1/2" x 3/4" connections
Situations requiring compact valve bodies for limited installation depth
Key specifications
Connection sizes: 1/2" x 3/4"
Valve body length: 40 mm
Function: thermostatic flow regulation for radiators and convectors
Suitable medium: hot water for hydronic heating systems
Application: mounting on standard radiator valve bodies for temperature control and isolation
How to use
Install the valve onto a compatible radiator valve body with the specified 1/2" x 3/4" connections, following local plumbing codes and manufacturer guidelines for sealing and torque. Set the desired room temperature on the thermostatic head (if supplied separately) and allow the valve to modulate flow automatically as the room temperature changes. Isolate the radiator using the valve when carrying out maintenance or system balancing; ensure the system is depressurized and cooled before removing components.
Usage recommendations
For reliable operation, use with clean, treated heating water and install appropriate strainers or filters upstream if the system contains debris. Periodic inspection and, if applicable, calibration of the thermostatic head will help maintain accurate temperature control. When replacing existing valves, confirm compatibility of connection sizes and mounting depth to ensure proper fit.
