## Long description

Comap thermostatic valve set PL809W5429 includes a 1/2" thermostatic valve, a W5 temperature actuator head and a 1/2" return (check) valve, designed for closed hot-water heating circuits. The set provides regulated flow to radiators while maintaining the selected room temperature through the thermostatic actuator. It is intended for installation on residential and light-commercial radiators where compact, reliable temperature control and backflow prevention are required.
Advantages
The integrated combination of thermostatic valve, W5 actuator and return valve delivers precise temperature control, simplified installation and protection against reverse flow. The W5 actuator responds to temperature settings to modulate flow automatically, reducing temperature fluctuations and improving heating comfort. The return valve prevents unwanted backflow, ensuring stable operation of the heating circuit and preventing circulation issues.
Suitable for
 Domestic radiators in apartments and houses
 Small commercial premises with hot-water radiator systems
 Replacement or upgrade of existing radiator valves for improved temperature control
Key specifications
 Valve connection size: 1/2"
 Includes thermostatic valve, W5 temperature actuator head and return (check) valve
 Application: closed hot-water heating circuits
 Functionality: flow regulation, automatic temperature control, backflow prevention
 Compatibility: designed for standard radiator connections with 1/2" fittings
How to use
Install the thermostatic valve set in place of the existing radiator valve or on a new radiator using the standard 1/2" connections. Mount the thermostatic valve body to the radiator inlet, fit the W5 actuator head to the valve spindle and connect the return (check) valve in the return line as required by the system layout. Set the desired temperature on the W5 actuator; the actuator will regulate flow automatically to maintain that temperature. Commission the radiator by bleeding air, checking for leaks and ensuring the heating circuit pressure and flow comply with system recommendations.
Usage recommendations
Use the valve set in systems with compatible 1/2" fittings and within the operating limits specified by the heating system manufacturer. During installation, follow local plumbing and heating codes and use appropriate sealing and torque values to avoid leaks. Periodically check the actuator for correct movement and the return valve for free operation; service or replace components if the system shows uneven heating or leakage.
