## Long description

Comap RK859724 thermostatic radiator valve set is designed for controlling radiator flow and regulating room temperature in hydronic heating systems. The set provides a connection interface between a 1/2" pipe and an M22 radiator inlet, enabling either manual or thermostatic control of radiator output. It is compatible with standard panel and column radiators and is intended for use where accurate balancing and simple temperature adjustment are required.
Advantages
The valve set offers reliable flow control and stable temperature regulation through a compact, serviceable design. Its construction supports straightforward installation on common radiator fittings and reduces heat wastage by allowing targeted adjustment of individual radiators. Materials and dimensions are selected for compatibility with typical residential and light commercial heating circuits.
Suitable for
 Domestic radiators in houses and apartments
 Light commercial premises such as offices and small shops
 Replacement or upgrade of existing 1/2" to M22 radiator connections

Key specifications
 Connection interface: 1/2" pipe to M22 radiator inlet
 Control mode: supports manual and thermostatic regulation
 Application: panel and column radiators compatible with M22 fittings
 Intended system type: closed hydronic heating circuits
 Typical installation orientation: inline with radiator inlet
How to use
Shut off the heating circuit and drain the radiator before fitting the valve set. Fit the 1/2" side to the incoming pipework and secure the M22 connection to the radiator inlet, ensuring appropriate sealing and alignment. After installation, refill and ventilate the system, then adjust the valve to achieve the desired radiator output. If used with a thermostatic head, mount the head according to the manufacturer’s instructions and set the required room temperature.
Usage recommendations
Check compatibility of radiator threads and pipework size before purchase. Regularly inspect connections for leaks after initial operation and during seasonal start-ups. When pairing with a thermostatic head, choose a head suitable for the valve stem type and allow free air circulation around the head for accurate temperature sensing.
