Key specifications

Connection size: 1/2" suitable for standard radiator inlet threads
Function: thermostatic flow and temperature regulation at radiator inlet
Design: compact valve body with components for manual thermostatic control
Application: compatible with domestic and light-commercial central heating systems

How to use

Shut down the heating system and drain the radiator area before removal of the old valve. Fit the FERRO ZTM20 valve set onto the radiator inlet using the standard 1/2" threads, ensuring correct orientation and tight, leak-free connections. Refill and purge the system to remove air, then adjust the valve to obtain the desired room temperature and balance flow between radiators. Periodically check for leaks and verify correct operation after system start-up.

Usage recommendations

For reliable operation, use the valve within typical hot-water heating temperatures and pressures specified for domestic systems. When replacing existing fittings, confirm thread compatibility and follow local plumbing codes. Regular inspection during seasonal maintenance helps ensure consistent performance and prevents leaks or blockages.
