How to use

Install the valve in place of an existing straight radiator valve or fit it during radiator installation at the 1/2" connection point following local plumbing practice. Ensure the system is depressurised and cooled before disconnection. Hand-tighten and then apply appropriate wrench torque to threaded connections using suitable sealing material as required by the installer’s standard. Use the manual control to open, partially close or fully close flow to the radiator for temperature balancing or isolation. After installation, bleed the radiator and check for leaks and proper flow.

Usage recommendations

For reliable service life, install the valve in systems with compatible water quality and follow regular heating system maintenance. If used in systems with aggressive water chemistry or abrasive contaminants, consult a heating specialist. During installation or replacement, verify compatibility with the radiator and pipework dimensions and use appropriate sealing methods to prevent leaks.
