Traditional rose head Victorian pattern radiator valves are available in an elegant polished chrome or polished brass finish. They are a thermostatically controlled valve and they keep the ambient temperature of the room where they are installed constant at the set value. They are supplied in pairs, a thermostatic radiator valve and a lockshield valve. The lockshield valves are installed on the return branch and are used for the hydraulic balancing of the circuit. Valves are available in angle pattern with ½” BSP male and ½” Irish size compression connections.
