## Summary description

Thermostatic 4-way valve by Comap designed for two-pipe heating installations. Features 1/2" thread and M22 floor connection, enabling temperature regulation and flow control between supply and return circuits. Suitable for radiator or underfloor segments in residential and light commercial systems where thermostatic mixing and diversion are required.

## Long description

Thermostatic 4-way valve Comap 1/2" M22 floor connection for two-pipe heating systems is a compact hydraulic component designed to control temperature and flow between supply and return circuits. Intended for use in two-pipe radiator and underfloor heating installations, the valve integrates a thermostatic element and four ports to mix or divert water flows, enabling stable temperature regulation and reduced commissioning adjustments.
Advantages
The valve provides precise thermostatic regulation and automatic balancing between inlet and outlet lines without the need for continuous manual adjustment. Its 1/2" threaded connections and M22 floor connection enable straightforward integration into existing piping layouts. The compact construction reduces space requirements and simplifies installation in both retrofit and new-build projects, while materials and design ensure reliable operation in low- to medium-temperature heating circuits.
Suitable for
 Two-pipe residential radiator heating systems
 Underfloor heating manifolds in small commercial or domestic buildings
 Applications requiring thermostatic mixing between supply and return lines
 Retrofit projects where compact floor connections are needed
Key specifications
 Connection type: 1/2" threaded ports with M22 floor mounting
 Function: 4-way thermostatic mixing/diverting valve for two-pipe circuits
 Application temperature: suitable for typical residential heating system temperatures
 Compatibility: designed for use with radiator and underfloor heating manifolds
 Installation orientation: floor connection with compact body for manifold placement
How to use
Install the valve in the manifold or piping run where mixing or diverting between supply and return is required. Connect the 1/2" threaded ports and secure the M22 floor connection according to the system layout and local installation rules. Fit the thermostatic element and set the desired temperature range or position per the system design; the valve will then regulate flow automatically to maintain the set temperature across the circuit. Commission the system by purging air, checking seals, and verifying proper flow direction and temperature response before regular operation.
Usage recommendations
Use appropriate thread sealant or gaskets compatible with potable water and heating systems. Ensure the thermostatic element is protected from debris by using appropriate filters or strainers upstream. Periodically inspect connections for leaks and verify operation after initial run-in and seasonal start-ups.
