## Summary description

Thermostatic axial valve Comap R807604, connection size 1/2" with flow coefficient Kv 0.55, delivered without factory preset. Designed for hydraulic balancing and temperature control in heating and cooling systems, it regulates flow in radiators, convectors and small circuits. Suitable for installation in domestic and commercial HVAC applications where precise flow control and compatibility with thermostatic heads are required.

## Long description

Thermostatic axial valve Comap R807604 1/2" Kv 0.55 without presetting is a compact flow control valve designed for hydraulic balancing and temperature regulation in heating and cooling systems. The valve features an axial design for stable flow characteristics and a Kv value of 0.55, making it suitable for precise control in radiators, convectors and small distribution circuits. Supplied without factory preset, the valve allows on-site adjustment and pairing with a wide range of thermostatic heads or actuators.
Advantages
The axial configuration provides predictable flow behavior and reduced pressure loss compared with some alternative valve types. A Kv of 0.55 offers a moderate flow capacity appropriate for individual radiators and smaller circuits. Delivery without presetting enables installers to perform hydraulic balancing on-site to match system requirements, and the valve body is compatible with standard 1/2" fittings used in domestic and commercial HVAC installations.
Suitable for
 Hydraulic balancing of radiator circuits in residential heating systems
 Temperature control in convectors and small fan-coil units
 Local regulation in commercial or light-industrial HVAC zones
 Replacement or upgrade where compatibility with thermostatic heads is required
Key specifications
 Connection size: 1/2" (female/male according to installation)
 Flow coefficient (Kv): 0.55
 Valve type: thermostatic axial valve, non-preset
 Application: heating and cooling systems, radiator and convector circuits
 Compatibility: designed for use with thermostatic heads and compatible actuators
How to use
Install the valve in the pipeline at the radiator or convector according to standard plumbing practice and system layout, ensuring correct flow direction. Connect the appropriate thermostatic head or actuator compatible with the valve interface. Because the valve is supplied without presetting, perform hydraulic balancing and set the required flow or travel stop on-site using recommended procedures and measurement tools such as flow meters or differential pressure gauges. Verify leak tightness and correct operation after installation, and commission the system following local codes and manufacturer guidance for connected components.
Usage recommendations
Use appropriate tools and follow applicable safety and installation standards. For accurate hydraulic balancing, measure actual flow and adjust the valve incrementally. When pairing with thermostatic heads, consult the head manufacturer's instructions to ensure correct mounting and setpoint calibration.
