Honeywell Valencia VTL120-15A 15mm TRV Radiator Valve & Lockshield Pack

This pack contains both a 15mm Honeywell Thermostatic TRV and a complimenting lockshield valve. The valve can be mounted vertically or horizontally at either end of a radiator

To work correctly, the Valencia Thermostatic TRV should be installed to a two pipe heating system and also have a free flow of air around the head to sense temperature

According to Building Regulations Part L1 thermostatic radiator valves should be fitted on “all radiators except in rooms with a room thermostat” to satisfy either Minimum or Best Practice installations
